TR6 Turn Signals/Hazards don't work

[BierRunner]

Went for a nice ride in my TR6 yesterday (total top down weather in central Ohio!). Checked that everything worked before I departed. After about 30 minutes, my turn signals stopped working (nothing, and same for hazards). I'm guessing a fuse but I can't seem to find a thread on replacing fuses, they are all much more substantial fixes).

Any advice?

If only the turn signals and flasher are out, it's probably not a fuse, as the same fuse powers a lot of stuff. Easy to check though.

Sounds more like a loose connection, possibly at the fuse block. Or maybe at the flasher switch.

You should get a voltmeter or at least a test light and a wiring diagram. Then trace through the circuit to see where you are losing power, and I'll bet the problem then will be obvious.

Does that mean you don't know how to change a fuse ?

Try cycling your hazard switch on/off several times fast.

Wow, tough love on the British Car Forum. I'm more of a driving enthusiast and less a mechanic, sorry about that, though I did find the fuse box.

Mainly, I was interested in which of the four fuses relate to the turn signal. There also seems to be mixed opinion about replacement fuses, with some going with US BUSS fuses (20 amp) instead of Lucas 35a fuses (which appear to be, despite their name, 17 amp).

I did find two spare fuses in the fuse box cover and tried them in all four slots with no success, so, likely, fuses aren't the problem anyway.

Thank you, I will try this next, once I acquire the voltmeter and diagram.

Apparently, the windshield wipers aren't working anymore either (they had been working but no more). Perhaps it's all related.

RGK, are you goofing on the new guy?

BierRunner It would help if you state what year you car is. Some things are different between early has a (rocker switch) and late (1976 like yours has a push pull switch) and the hazard switch is one.

scroll down to your year.

Nope, the internal connections can stick and cycling the switch sometimes gets it going again.

Thanks for sharing the diagram. The turn signal and hazard are on the same line.

Alright, I’ll give it a try. Thanks!

Consider getting the Yellow Book, 'Triumph TR250 -TR6 Electrical Maintenance Handbook' by Dan Masters. Great for understanding , trouble shooting and repairing.

Sure enough, this little trick worked. Thank you so much!

I am also the proud new owner of a voltmeter. So I’m ready for the next time.

In case it does not work next time, these switches are not difficult to repair, just caution with the plastic is advised. There is a how-to somewhere, if I find it I will post here. I had lots of experience with them on a S2 E-Type, it had ten of them, although they were very easy to get to.

Hazard switch repair link. The other switches are similar. I use a hairdryer to try to prevent plastic breakage. Masters manual also has repair info.

Don't forget to disconnect the battery before sticking your hands under the dash
