    123 have just released an update for their app so it’s all working again.

    yes it was a bit of a worry, car immobilised with the app not working ! 
     

    I will now download the app on an old phone for contingency

    I wonder if they’ve made the Google version of the app work as it was pants ! …

  4. Intermittent wipers, with wash wipe too !

    in General TR Technical

    Posted · Edited by Steves_TR6

    Hi Bob

    the instructions are specific to the tr6, they will not work for a tr3

    on the tr6 the park wire from the motor is connected to the low speed feed to the motor when the wipers are switched off, this is how the park circuit works

    the relay is effectively a spdt switch controlled intermittently 

    The spdt contacts are 53m is the centre contact, 53s is NC and 15 is NO

    thus my design replicates the tr6 switch effectively switching from off to slow briefly to start each intermittent wipe, and utilising the park circuit to complete the wipe. 

    your challenge will be triggering the intermittent function, as there is no trigger reaching the switch you’ll need to wire to the motor and pickup the segmented earth park contact,

    also the relay unit fundamentally wants to switch a positive feen not a negative, so i think you’ll need a power transistor or similar to switch negative.

    should all be doable but i don’t have an early car to experiment on

  5. P.I. injectors

    Much safer to test them one at a time in as I said using a Jam jar with the injector through a hole in the lid. 

    That’s what i do, on a running engine.

    first remove all the keeper plates and jiggle the injectors to make sure they are free to pull out

    start engine

    extract each injector in turn and point into jar, see if there is a cone of spray

    if no cone of spray then gently tap the injector and or very gently pull the spring loaded end of the injector with the injector pointing upwards to allow air to exit

    at this stage the injector either starts working in which case reinsert it , or it doesnt and needs replacing

    work your way along the 6 

    this process has either fixed the problem when the issue was just air in the system or identified the tired / failed injectors every time i’ve done it

    only take 20 minutes, and with a fire extinguisher at hand and ideally a second person to start/stop the engine is pretty safe

    Haha, Vegemite is nice but i’m a marmite man

    only this afternoon I did an injector test on a member’s tr6 and found 2 recalcitrant injectors, we used a small pyrex jar which worked well

    we’ll be ordering a set of refurbed injectors from Neil Ferguson, he’s served me and many others well for many years with PI parts.

  9. Tr6 wiper wiring, explanation and how to add WashWipe relay.

    in General TR Technical

    Hi Dan

    i did not supply you with one of these units so i do not know for sure which you have.

    from the photos it appears to be an SE unit, as it has a blue washer feed connection ( not the thin black of the fe unit)

    If so you appear to have connected it correctly , being

    Disconnect the brown/green park wire from the first switch contact (small spade) and connect it to the green/yellow wire of the se unit

    disconnect the red/green wire from the second switch terminal and connect it to the green wire of the se unit

    connect the red wire from the se unit to the now vacant second terminal of the switch

    connect the blue wire of the se unit with the light green/black wire in the centre of the switch

    connect the black wire from the se unit to a good earth point.

    do not touch the blue/green wiring to the fast wipe circuit.

    if this is what you have done and fast wipe is not working correctly, then i’m at a loss and can only suggest there is something non-standard with your wiper motor wiring

    as i’ve said already the units do not touch the fast speed wiring so it’s impossible for fast to be affected, unless there is something different about your car’s wiring, they are old cars after all !

    If you can’t make it work then return it and i’ll refund the original purchaser, whom i assume is Harry ?

    I have the 123 Tune + fitted and really very pleased with it.  Had the tacho converted to electronic by  JDO Instruments (www.jdoinstruments.com).  Think the cost was £150 plus postage.

    Same here and very happy with it after a few years.

  12. Tr6 wiper wiring, explanation and how to add WashWipe relay.

    Hi Dan and Darren

    i suggest you check the fast wipe in isolation.

    the switch terminals are :

    1, small spade connection to park switch

    2, slow wipe connection

    3, 12v ignition switched feed

    4, fast wipe connection

    in the ‘off’ position the switch  connects park and slow to park the wipers

    in the slow position it connects slow and 12v to power slow wipe

     in fast it connects 12v and fast for a fast wipe

    my relay just interrupts the slow wipe and park, it doesnt touch the fast wiring.

    to test the fast wipe just disconnect the fast wire from terminal 4 and connect it to 12v, having lifted the wipers from the screen they should go ‘fast’

    good luck!

    steve

    ps, i tested the units on my cr tr6 and they worked correctly, including fast wipe

     

  18. Tr6 wiper wiring, explanation and how to add WashWipe relay.

    Hi folks.

    i’ve received a request for further explanation of the TR6 wiper wiring, and specifically how to integrate the WashWipe controllers i recently produced.

    so here goes !

    The TR6 wiper circuit is actually quite sophisticated.

    previous TR models just switched the earth side of a one or two speed motor, and had a simple park contact to complete the wipe when the switch was turned off

    Not the TR6 though !

    for the 6 the positive side of the circuit is switched, and the park circuit included a clever electronic brake to stop the wipe motion dead in the park position.

    here’s a diagram i cobbled together from online sources and added my own descriptions :

    6BDA3744-2B93-4DE9-93B6-3402A3BBD089.jpeg.6bbbaddf593bb64551c4d43407c5ef62.jpeg

    The diagram shows that the Park switch provides 12v to to low speed circuit if the wipers are NOT PARKED, but 0V when they ARE PARKED

    this causes the energy stored in the motor windings to collapse and stop the motor dead ( its the same way that the ignition coil works)

    this clever circuit also allowed me to utilise the change in polarity of the park circuit to trigger the Intermittent Wipe relay that i produced which should be wired in thus :

    DB02E8A8-6195-4670-AA54-8C63AAE6100A.jpeg.a73c83331aa10f74ecc1680eb53bf6ae.jpeg

    wiring to the original low speed circuit is intercepted by the unit, thus replacing low speed with intermittent

    The park feed from the motor is disconnected from the switch and routed instead to the controller

    Fast speed should not be touched and remains unaffected

    I hope the above is informative and useful for those messing with TR6 wipers, either with my TRIWW units or otherwise

  19. 123 Electronic ignition

    anyone help me with the 123 Ignition system Model 123\Tune + 6 .  It is the blue tooth version.  How can that be fitted to my 1973 TR6 when i have a mechanical drive for the tacho?  Is there an alternative 123 model that would work?  I have asked 123 ignition Co the same question but no response to date.

    Many thanks

    I have the 123tune+ on my 6 for a few years now and its worked flawlessly

    i did have my tacho converted to electronic by JDO, and that works perfectly too, better than before actually!

  21. Just bought a TR6

    Hi,

    When I bought mine I went over it checking every nut, bolt, hose clip, clamp etc. for tightness/condition and was surprised by what I found. The simple act of putting a spanner/screwdriver to something helped me “see” things rather than just “looking” at them. Worked well for me and I found nothing too alarming but found it a great way to get to know the car. 

    I agree, and also take a good look at any electrics that have been added over the years !

    I removed many metres of dodgy electrics from both of my TR6s when i bought them :-)
