  1. This topic has been prompted by wiper-brush kits becoming available on eBay for much lower prices than hitherto, £12 as against £25 or more. And I bought a DR2 from 1958 with the classic destroyed commutator, caused by running with worn-out brushes. A few years back I'd have to store a motor like this until a new armature turned up. Both DR2 and DR3A wiper-motors will run to destruction without carbon-brushes. This one was running OK, if a bit squeaky. Then I bought some commutators from the US and could fix them. But after shipping, import cost and VAT these worked out to cost around £10 each. Now I can get them on eBay from China for less than £3 including shipping. And very good parts they are too. The photos are largely self-explanatory I think. Except photo 3. I get the old commutator off by crushing in a vise. You can see that only a few thou of copper remains and if run a little longer this would all come apart. More or less anybody with a soldering iron could do this job and it would take only an hour or so. The last photo shows the front area of shaft where the bearing runs. Even after 60 years of hard life I cannot measure any wear here. They are usually like this. Whereas NOS ones in boxes are often rusty, even if advertised at £100 or more.
  2. Hi all, went to the garage to start the car and it won't start! It is a 73 PI CR engine with a Luminition system which I fitted 5 years ago and has worked perfectly until now. I turn the ignition on and there is 12v at the coil, I then start churning the starter motor and the voltage at the coil drops to about 9 - 9.5v. The engine does not fire, when I release the ignition switch the engine fires on the release and tries to start???? If it fires successfully the engine runs OK. I do not think there is any spark while the starter is churning but is a bit difficult to see as I have only one pair of arms!! I am assuming it then sparks as the ignition switch is released any ideas?? kc
  3. Hi all Im trying to source some cibie headlights. Looking at past threads 082441 seems to be the right part number but it seems they are no longer available. Ive ordered a couple of times only to find the order cancelled because they cant get hold of them. Ive got them on my TR4 and looking for some for my GT6. Any help appreciated. regards Bob

    Horn fuse blowing

    More electrical gremlins on my 73 cr tr6! My horns stopped working and I found the fuse -35 Amp had blown. I replaced this and all was well. I checked for any obvious wiring issues and found none. On taking car for MOT I checked horn on the way and found fuse had gone again! I replaced fuse just before reaching the MOT station and it lasted for the test however by the time I got home the fuse had gone again! This fuse covers the horns,all interior lights and the headlamp flasher. All bulbs on interior lights (underdash, boot) are not fitted at the moment. the glove box bulb operated ok when I earthed it (Switch missing). The interior light switch is not fitted at the moment and connections are insulated. So far I have checked that the circuits from the fuse are not showing a leak to earth by putting a test lamp on them with a feed directly from the Pos battery terminal. I have also checked that the horn push is ok by removing the trigger connection from the relay and using a test lamp. I have taken apart the Lucas relay and could find nothing wrong and no sign of shorting. I have checked all the bulb holders and no sign of shorts. The headlamp flasher operates correctly( new switch). I have been unable to replicate fuse blow in the Garage even with ignition on and lights. Before I start an autopsy on my wiring loom, has anyone had the same problem? I must be missing something !!! Any words of wisdom as ever, very gratefully accepted !! MARK
  5. Hi, Just wondering if anybody could point me in the right direction to buy a coloured wiring diagram for my TR7 1981 UK car. I have unfortunately tried to use the many websites that advertise TR7 wiring diagrams under google images , but most if not all turn out to be scams looking for payment card details and hidden monthly subscriptions. Very frustrating for your average classic car enthusiast. Any help would be greatly appreciated Thanks in Advance Paul
  6. Hi I tried to start my TR5 which had been stood for a while and found whilst the battery was allowing the Bosch fuel pump to whir when I turned the key there wasn't enough juice in the battery to start the car - no surprises there. However having removed the battery, charged it up etc I then turned the key to find that the fuel pump is silent and clearly not working so the starter motor is clicking away with no fuel coming through. I have checked the fuses, I have checked all the wires connecting to the fuel pump but can't find any obvious issues. Seems very strange when all I have done is remove and replace the battery after charging it up. Any thoughts/assistance? Thanks a lot Best Sean
  7. I've been busy the last couple of days re modelling my TR6 loud speaker pods. I had bought and fitted Moss supplied pods at least 20 years ago with locally supplied Alpine speakers. Many years of activity, (you don't have to ask!) had taken the toll on the integrity of the hardboard backbone as highlighted in the attached photo. They also had a mind of their own and often fell down into the footwell. The used of cable ties and gaffa tape to hold them in place was never pretty. My wife bought me a Stanley staple gun for my birthday in August, and naturally I knew exactly where it was going to be used first. I have remodelled a pair but with thought for robustness and price. I have used 5mm plywood from B&Q and resourced off cuts of vinyl and a combination of 1" and 0.5" foam to suit from 'Thames Upholstery' here in Southend on Sea, Essex very generously given to me at zero cost! I used the original hardboard as a template, out came my hardly used jigsaw and copies were made. Everything else more or less fell into place, and as you can see from the photos, job done! The sound from these speakers was never that great with a distinct lack of bass as there is no baffle. However the rigid construction of these new pods has helped the sound to a small degree. They were a little tricky to get into place as the plywood does not offer much flexibility, but where there is a will, there is a way! So for the cost of less than £10 I'm very pleased with the end result. Only one downside, the 20 year speaker covers are not like new, oh yes there's always Ebay!
  8. Hi Folks, yesterday I renewed the battery on my '64 TR4 and the guy tested the battery under load [engine running, lights on]. It gave 13.8 volts so all well. However, the alternator conversion is causing the ammeter to give a significant apparent discharge. Does anyone have details of wiring which correct the ammeter reading to include alternator input? Pic attached of the ammeter with engine running and lights on. Best wishes Willie
  9. I am thinking of installing electronic ignition to my '72 UK Dec registered TR6. Looking for any advice on which is the best and the best value for money and tips on fitting. Thanks, Andy
  10. The indicators have stopped working on my 1974 TR6 can you please give me some advice on how to troubleshoot this. The flasher unit looks new - its round not oblong, but of course that doesn't mean it is working. I also dont know if this is important but when I tried the indicators in the garage there was a click on the passenger side behind the dash and then nothing. It hasnt done this again turning the ignition switch on and off. The fuse is ok. Could a blown bulb cause the problem? I'm not an electrician but I know how to use an ammeter and follow basic instructions. Any help would be appreciated. Cheers Rob
  11. Since I wrote about wiper-motors in TR-Action it's probably no secret that I rebuild the early Lucas wiper-motors. About 10% of those that come my way have a problem with the armature. This is not a problem with the DR2 type, because I have a good stock of new armatures for these, left over from other activity. Ask if you need one. But the more common DR3A type armatures are a problem to get. Now and again I get lucky and find one for £20. Sometimes I get forced to pay £40-50. This really makes a motor rebuild uneconomic. Even if I find an NOS one there is no guarantee it will be in good shape. Often they have rusty shafts and other corrosion, having sat too long in damp packaging. Anybody on here who finds he has a commutator ploughed up by the brush arms, will be in the same position as me. Except I'll be on eBay bidding too. Apart from damage from being run with worn brushes, there is the dreaded "black-wire" problem. Here is one I fixed recently for a Register member: This happens if they are powered up, but stalled or jammed for any reason. At least 10A will flow and the temperature gets high enough to melt the solder joints. You can see this on one of the tags. This is the inside of the motor. You can see the witness left by evaporated varnish: Armatures like this continue to run. May do so so for quite a while. Annual MOT and running about to summer shows and you'd be OK, most likely. But one dark wet night on the motorway and after running hot for a few hours, don't bet on it. I DON'T SELL THESE. No doubt many others on eBay would. Be careful ! So I have a dozen laying about and a worsening supply problem. I asked every motor rewinding-shop I could find, to quote for rewinding them. NOT ONE REPLIED. I am rather glad they didn't bother. The reason is that they know what I now know. It's not just the wire. The copper commutator-segments are moulded into the phenolic bush. This is probably the hottest spot. When you strip one down this happens: This is probably a more likely cause of terminal failure than the wire. A segment gets loose, catches the brush and game over. Rewinds are POINTLESS on these, unless you fit a new commutator. Nobody has these, which is why nobody would quote me. To be fair I asked in the RFQ for new commutators, just to shut out the rogues. I thought about making new commutators. I'd do this if I just wanted one, maybe! I considered other things like nicking them from DR2's. These are not exactly the same but close. I could get them off but I'd scrap the shaft. It would mean lathe-work and this would be slow. Then I found these: New, not identical, but very close. They would be cheap too, were it not for shipping, VAT, customs-handling etc. i took a £100 punt and got ten. All the ploughed up commutators got fixed in an afternoon. Four perfectly serviceable armatures from the scrap heap, economic even if I count labour at a commercial rate. Brilliant! Now then, what to with the black-wire ones? You can all guess what comes next I expect.
  12. Hi, I've done a forum search and a general google to try and answer the question I'm about to ask but end up going around in circles and getting more confused so I'm hoping there's a straightforward answer. I've got standard rear bulb holders and struggling to get a decent earth. I've run an extra ground cable to each bulb holder but still only some of the lights work consistently. I've read about people soldering an extra tab to the bulb holders, and others using stag bulb holders. My question is, do all stag bulb holders have the extra earth tab fitted as standard? Thanks, Steve
  13. Hi All Some more advice please. My car has not run in a long long time, in reality it probably ran for less than 15 years before being taken off the road. So I’ve got what appears to be an original Lucas distributor. Do I just clean it up stick in new points and a condenser and put it back or get it refurbished by Distributor Doctor (or similar) or exchange it? (any other suggestions welcome) What slightly puzzles me is that if Distributor Doctor refurb it that’s £195 but if Moss (not usually that cheap) supply a refurb one on exchange its £165. I’m tempted by the Moss one but has anyone any knowledge or experience of the quality of the work or know who they use to rebuild? Cheers Keith
  14. Hi All Any wiring experts out there. Having a few issues with this bit. It might be my lack of knowledge or me not being able to read a wiring diagram, which is not good when trying to rewire a car, Lol. So I’ve got 6 wires go to the IGN switch, it’s a 72 so its under the steering colum. There are 3 white, 1 white red trace and two brown white trace. Now according to the wiring diagram (advance autowire version 1972 model) there are 4 connections, as per rear of IGN switch with the brown/W to a common connector the 3 white to a common connector and the White red on its own so one unused. No prob that makes sense. But which connectors? The diagram in the brown book shows them but does not say which wire goes to which connector, unless I assume the Red white goes to the single. Given that on the physical switch the connections are numbered (See pic) does anyone have a definitive list of what wire goes to what number connector? Clearly those connections will determine what is “on” at each different position of the IGN key so if anyone can also supply or direct me to a list of what works and when that would also be great. I think I’ve tried every combination and its got it working but not quite at 100%, so its either wrong or its right but I have another problem affecting these wires as well. Cheers Keith
  15. I have a 45 amp alternator with a voltmeter fitted but have a bit of a worry Most of the time it reads 13.5 volts At 2000 revs With Revotec fan running it drops to just under 13 volts With headlamps (Osram night breakers) on as well it drops to just over 12 volts At idle with everything on it reads just under 12 volts Is this normal? Im in a quandary as we are off to Angouleme very soon and returning via the Italian lakes and Switzerland, so a lot of driving in the Alps. Do I Leave it as it is Buy an 18 ACR alternator (45 amps) from Moss tomorrow Fit a 55 amp alternator If the latter where is the best and quickest place to purchase one that will be a direct swap. Thanks for your help Nigel
  16. Hi all, I am installing a new loom in my TR4, I have changed to an alternator. I assume I change the old dynamo regulator to a alternator regulator ? also do I need to upgrade the fusebox ? Regards Ron
  17. Hi All Still on going with the electrics and one thing that i didn't do but would be a good idea is bench test my starter motor. Si I stripped it down and cleaned and tidied it up and all looks ok, but i guess i should test it to see if it actaully works. So i'm not 100% sure on how to do that. Clearly i would put a live feed to the top electrical input on the solenoid but i know that won't do much until the White / Red Trace wire from the IGN switch powers and tells the solenoid "GO" So can i use any old live feed for that or does it need to be a specific current to trigger it? Seems sensible to bench test it as i can then see if anything at all is happening. Cheers Keith

    Fuse box

    Hi all, just going to install the fuse box but in looks knackered, so going to buy a new one should I take the opportunity to put a bigger capacity unit in for future add ons and if so what size 6 way, 8 way ? Regards Ron
  19. Went for a blast in the TR250 to calm down after after posting about the latest bod problems and the fuse blew when I flashed my headlamps. The flasher, stereo and 12v accessory socket share their own unique fuse and the lighting switch is column mounted so changed the fuse, tested the flasher and the fuse blew. After lots of stripping everything down (what a pig of a job to access the wiring under the colum and remove the switch - thinking of leaving the cover off and use cable ties!) all the wiring appears fine - no breaks or dodgy insulation. By accident I discovered that the outer casing of the switch is permantly live when all wiring connected. If I disconnect the brown wire which supplys the power to flash the headlamps the outer switch casing is no longer live. I assume this is the problem but cannot see anything obvious and it looks impossible to take apart without breaking it. A new switch is £60ish so any ideas before I go to Moss on Tuesday. Was hoping to use the car this weekend but dont fancy putting everything back together and then stripping it all out again. Cable ties are looking more and more attractive. Cheers Nigel
  20. Hi, Moved on to the interior of a long 74 TR6 restoration project. Got a new wiper/wash switch, the big round one that pushes and turns not a rocker. Trouble is it doesn't come with the fixings, numbered 81 to 85 in the Moss book. Have tried all the usual suppliers, including those who deal in second had parts with no luck. Does anybody know where i can get these or any other suggestion. If not does any body know the thread size and type on the switch as will try and make something. tried lots and nothing seems to fit and have to be very careful due to the soft plastic. Thanks Dave
  21. Before I begin this post, I am aware that the newer fuse ratings are continuous and not blow. The question therefore is fuse ratings in 'old money'. The TR4/4A workshop manual states that the fuses in the fuse box should be 25A blow (12.5 continuous) but both Rimmers and Moss are selling 35A fuses for both the TR4 and 4A (I am assuming for the sake of this that these fuses are 35A blow). The only fuse that is 35A blow 17.5A continuous in the workshop manual is the horn fuse. Consequently I have been using 25A in the fuse box (with no problems). Usual reason for a fuse to blow is a short to earth and both a 25A and 35A would blow in that instance. Just wondering when it was decided by the 2 suppliers mentioned that it was ok to fit the 35A (blow) in place of the 25A (blow) mentioned in the workshop manual. Unfortunately the TR4A handbook fails to state the fuse rating. The Haynes manual follows the workshop recommendations. I have also got the TR4/4A owners workshop manual by Kenneth Ball (Autopress) and that also states that the fuse carrier has 2 x 25A fuses and the horn is 35A (again blow rating). Does it matter which fuse is fitted? Personally I am sticking to the 25A fuses to err a bit on the safe side. (Rather blow a fuse than cook the wires). Also does anyone have a quick DIY way of telling whether a fuse marked simply 35A is blow or continuous. Presumably the 2 types have differing resistances but the resistance is too low for a standard ohmmeter to differentiate. I have tried a simple Wheatstone bridge and a simple Kelvin bridge arrangement to compare fuses with no success. I have a few of these fuses that I might end up ditching because I can't tell what they are. Keith
  22. Hi everybody Kenlow fan controls are good because they have an automatic function when the water temp gets too high and a manual override and a fan teltail light to enable the driver to manually switch on the fan and also be aware when the fan is running very good but the fiddle of getting a copper tube into the upper waterways is difficult and difficult to seal What other methods are used to give the auto control with manual override and tell tale light? I have used kenlows for years but feel it might be time to move on Would appreciate more modern solutions that others have found to work Hopefully MichaelH
  23. Hi all I have a 1972 PI with ignition on the steering column. I discovered the other day that the spring that returns the ignition key from "start" to "run" appears to have failed. Before going the whole hog and replacing the ignition unit (which seems like a sledgehammer to crack a nut) I want to remove the ignition barrel and do some investigation. Plenty of instructions on how to do that, but I can't for the life of me find how to remove the padded trim around the keyhole. How is it fixed - I don't want to force it. Any guidance gratefully received!

    Washer Bottle

    Hi All Was going to pop my refurbished washer bottle back on my resto project. Looks nice and clean with repainted bracket and home made strap. Cleaned all the motor up before giving it a test and err dead. So should it work by just connecting to a 12v, i would assume it would, but no. Completly disasambled it and it looks fine to me and the motor spins freely when the shaft is spun, but clearly i know nothing. So any tricks to get and old electric motor such as this kicked into life? I've had a look at the usual retail suspencts and this type of motor (see pic) seems unavailable only a Lucas GWW125, which although cheap as chips is the wrong shape and i'd prefer to get this one working. Cheers Keith

    More Electrics

    Hi All In my "Fuel pump electrics" post i also asked the question "On a similar (electrical) but unconnected note whats the best way to test my "Highly Professional" installation? lol." "Do i just stick a battery on and see if the lights work, things like the fuel pump feed i guess i can check via a multimeter." Well all i can say is Whoa, let there be light!!, lol. Keith
