Left turn signal quit working

Post by arnoldlatzke »

My left turn signal went out.  Not sure if it had anything to do with riding in the rain for 5 hours.


Question -


If a bulb goes out, will it stop the turn signal from working?
Has anyone else had this issue with a fix ?

Removing the rear RHS turn signal bulb will prove whether or not a bulb out will stop the turn signal from working.

I had a similar issue. Tried the hazard lights - bulb was fine as all 4 indicators worked fine.
Disassembled the multi-switch as far as I could. Somehow my model doesn't seem to have a screw underneath the label on the underside (handle bar facing) side of the switch.
I got the orange plastic part and silicon seal off and loaded the switch with WD-50 and ACF-50. After a few hours and some repetitions I pressed the switch many, many, many times and watched the indicator slowly coming back to life.
