Riddle me this

[weiser23]

I replaced my turn signal flasher and after awhile my turn signals will work a then not, I go back and forth right and left and sometimes it flickers some times not sometimes it go on for awhile then flicker and goes out, I thought it might have something to do with how much voltage is in battery but if there’s enough to start the bike it should be enough to light two bulbs,

What bike is this on? Does it have LED lights? If so do you have the right type flasher for LED?

I would guess either a loose connection or a bad switch contact. They are switched to ground so one relay and contact set operates both. A simple continuity test at different points in the circuit should reveal the location easy enough.

I agree with the poor grounding connection somewhere. Or just a slightly loose connector.

This is it. The turn signal system in these bikes (and all bikes) is not nearly as complicated as people make it out to be.


Here is a complete interactive circuit diagram that I love to trot out in situations like this. That's all there is in there.
