Turn signal stumper

All of a sudden my left turn signal on my 75/6 won't work. Neither the front nor the back. I checked the wires and the fuses and can't find anything wrong. They were working fine yesterday now nothing. Any suggestions?

How about the switch? Can you reverse the leads on the relay to test the left side using the right throw of the switch?

I'd also check the relay. Of my three /6's, I don't have one decent relay. The best one you have to jiggle every once in a while to get the turn signals to work right.

yeah its probably the relay. the front one used to not work while the bike was off, but would work when it was running. The back always worked. I just put in new LEDS in the back and they were all working fine. Now the back led yellow comes on but doesn't blink and the front doesnt come on at all. I hate wiring :)

The left turn signal on my 90/6 just started to go on the fritz too. I can get it to work if I find a sweet spot on the switch itself which it never required before. It only gets ridden a dozen times a year.

Could this too be the relay? Hrmmmm

The one on my 100/7 has just failed. Indicators flashed but the warning light stayed permanently on. New transistors to sort it out cost $1

Put the stock bulbs back in and see what you get. It could be the flasher won't work reliably with LEDs.

Thanks for all the suggestions. Here's what the problem was. The ground wire inside the light is attached to a metal bracket. That metal bracket must be touching the metal post that the light housing slides onto. That is apparently what causes the grounding to the bike. Being 30 years old the light housing is lose on the bracket and you can rotate it up and down and wiggle it around. Apparently it had become so lose the metal bracket was no longer touching the metal post, therefore no ground, ergo no blinker. I used a little glue to tighten up the light housing so it doesn't wobble around and problem solved.
