Richard71 Posted February 14, 2016 Report Share Posted February 14, 2016 Hello All, I'm trying to source a more reliable 2 pin electronic flasher relay that will slot right into the existing rectangular bracket on my 1972 TR6. I've looked up all the usual places and can only find circular units. Does anyone know where I can find one? Thanks in advance, Richard. Quote Link to post Share on other sites
TriumphV8 Posted February 14, 2016 Report Share Posted February 14, 2016 I fitted a 3-pin relay, the new pin is simply ground that can be connected by the screw that holds the little connector in place that bolts the flag of the relay. Just a little work to make those parts and drill a hole but its quickly done and those relays are cheap and widely availiable.... Quote Link to post Share on other sites
jerrytr5 Posted February 15, 2016 Report Share Posted February 15, 2016 I don't think you will find a 2 pin electronic unit. They use the third pin for a an earth in order to function, otherwise it will just be a bi-metal strip. Jerry. Quote Link to post Share on other sites
RogerH Posted February 15, 2016 Report Share Posted February 15, 2016 (edited) Would this do http://www.ebay.co.uk/itm/2-Pin-Electronic-Flasher-Relay-TRIUMPH-TR3-TR4-TR5-TR6-/151398990423?hash=item2340154257:g:-AYAAOSw-jhUBD4g Roger oops -its round.

Fireman049 Posted February 15, 2016 Report Share Posted February 15, 2016 Hi Roger ~ What would be the advantage of fitting the two pin electronic flasher unit to my 3A? What about the three wires? Cheers ~ Tom. Quote Link to post Share on other sites
RobH Posted February 15, 2016 Report Share Posted February 15, 2016 Tom - there would be no advantage. There are plenty of three-pin electronic flashers which will fit directly to a 3A, like this one for instance: http://www.autoelectricsupplies.co.uk/product/165/category/35. To use a two-wire flasher you would have to do something to connect the dashboard lamp. It would need two diodes and a bit of soldering. Quote Link to post Share on other sites
Fireman049 Posted February 15, 2016 Report Share Posted February 15, 2016 Thanks RobH ~ I'll stick with what I've got. Cheers ~ Tom. Quote Link to post Share on other sites
RogerH Posted February 15, 2016 Report Share Posted February 15, 2016 Hi Tom, the two pin is used on the TR6. The switch arrangement on the 6 is different to 3/4/4A. Stick with the three pin (plus earth) for your car. Roger Quote Link to post Share on other sites
Richard71 Posted February 15, 2016 Author Report Share Posted February 15, 2016 I was really hoping to find a direct rectangular, (upgraded) electronic replacement. So, will any 3 pin electronic unit do so long as the third pin in earthed? Richard. Quote Link to post Share on other sites
RobH Posted February 15, 2016 Report Share Posted February 15, 2016 So what do you find unreliable about the original bimetallic type Richard - have you fitted LED bulbs or something? Quote Link to post Share on other sites

Hi Rob, I'm not aware of any unreliability with the bimetallic unit, I just though an electronic unit would be more reliable. Regards, Richard. Quote Link to post Share on other sites
Guest ntc Posted February 16, 2016 Report Share Posted February 16, 2016 Richard They do not as does those from Moss ,Rimmers and the rest,Autosparks do. Quote Link to post Share on other sites
Richard71 Posted February 16, 2016 Author Report Share Posted February 16, 2016 Neil, I can't make a blind bit of sense from what you've just posted.......care to elaborate? Richard. Quote Link to post Share on other sites
Guest ntc Posted February 16, 2016 Report Share Posted February 16, 2016 Richard I had recommendations from one and all some time back and all was put in the bin Autosparks one was fine and still is.Got it? Quote Link to post Share on other sites
paul7 Posted February 17, 2016 Report Share Posted February 17, 2016 Try Gil at Better car lighting 0121-7737000 I had one off him sometime ago when I fitted LED bulbs in the rear. I seem to remember it was a straight swap. Anyway its been fitted over 12 mths with no problems. His bulbs are good quality as well, but not cheap Paul Quote Link to post Share on other sites
DRD Posted February 24, 2016 Report Share Posted February 24, 2016 Would this do http://www.ebay.co.uk/itm/2-Pin-Electronic-Flasher-Relay-TRIUMPH-TR3-TR4-TR5-TR6-/151398990423?hash=item2340154257:g:-AYAAOSw-jhUBD4g Roger oops -its round. I got this - its works well, a much more consistent flash speed on both sides. Quote Link to post Share on other sites
Graham Posted February 24, 2016 Report Share Posted February 24, 2016 I got this - its works well, a much more consistent flash speed on both sides. Did you use ballast resistors as well or just the flasher unit ? ATB Graham Quote Link to post Share on other sites
RobH Posted February 24, 2016 Report Share Posted February 24, 2016 I think we need to put this 'ballast resistor' thing to bed once and for all as it seems to crop up quite often lately. You should not need extra resistors unless you are using the wrong flasher unit with LED bulbs. You will need them if you are using LEDs with the original bimetallic flasher. You will also need them with LEDs if you have an electronic flasher designed for use only with ordinary bulbs, if that incorporates a blown-bulb current sensor as some standard ones do. ( It mimics the old bimetallic type by flashing faster if it senses insufficient current drawn) You will not need them if you have an electronic flasher unit designed for use with LED bulbs. You will not need them for an electronic flasher with ordinary bulbs. Quote Link to post Share on other sites
DRD Posted March 4, 2016 Report Share Posted March 4, 2016 Did you use ballast resistors as well or just the flasher unit ? ATB Graham No - I just did a like for like swap. Quote Link to post Share on other sites
