A bit of a weird one with my 2016 Piaggio MP3... My driver's left side turn signal (front and back) will not go on once the bike gets warm. The turn signals only work for the first two-three minutes then they no longer function.
What I have done to troubleshoot:
- I switched the bulbs from the right (working) to the left and vice versa to confirm the bulbs are good. I even tried newly purchased bulbs.
- I checked using the hazard buttons, but the same thing. It only turns on the left side for the first few minutes.
- I checked the fuses corresponding to the turn indicators, all good there. Again swapped the fuses and even tried new ones.
- I took apart the assembly and checked the function of the switch by completing the circuit with a wire. The right side turns on but the left side does not. I checked it with a multi-meter and the wiring for the left side does not get power.
Based on the above, I am guessing it is a relay? Why would it only work for the first few minutes though...
Any ideas/suggestions for things I can try?
