luukkala Posted July 20, 2016 Report Share Posted July 20, 2016 Hi, Looks that I have an electric fault on my 1974 TR6: The signal/turn switch in steering column starts smoking when I'm starting the engine. The smoke is coming from the switch itself rather than from wiring. When this occurs the signal relay goes on although the switch is not on in any turn position. Is this a common problem? I believe the switch itself is worn out and needs to be replaced. Cheers, Tommi Quote Link to post Share on other sites

One might have come loose and you may be able to epoxy glue it back. A replacement would be a good idea. It was never a good design in my view. Peter Quote Link to post Share on other sites
ianhoward Posted July 21, 2016 Report Share Posted July 21, 2016 (edited) I had exactly the same issue a few weeks back... I took the switch out, thoroughly cleaned it with electrical cleaner, connected it up again... and it was worse with genuine period Lucas smoke and sparks!!! So purchased a replacement! All appears good now though subsequently had issues with the electronic flasher unit that kept blowing the fuse. Well, I believe that is the cause and haven't been able to thoroughly verify as had to return to work away from home...

luukkala Posted July 21, 2016 Author Report Share Posted July 21, 2016 Hi, I tried with a cleaner already, no success --> looks like the unit needs to be taken apart. Must say the unit looks quite solid and bit surprised in case the unit can be taken apart. Will try that as next step. Thanks for the advices! -tommi Quote Link to post Share on other sites
ed_h Posted July 21, 2016 Report Share Posted July 21, 2016 Don't lose the screws that mount the switch. They are an unusual 8-36. Ed Quote Link to post Share on other sites
