Left/back turn signal not working

[simontb_denmark]

My turn signal (left/back) is not working. All the front ones work and the right/back is also working.
When I start the signals on the right side, they blink fine.
But when I start signals on the left side the font one light up, and stays on. The back doesn't turn on. I guess the relay need a certain amount of power to turn off and on.


When I measure the volts in the rigth/back one, it says 12 volts, when blinking - all is fine.

Then I measure volts in the left/back one it says 7-8 volts.

Any ideas on how to fix this? I cleaned my connections but with no result.

Hi !

Is the bulb itself okay ?

Are you getting 12volts to the left/front?

Could be a dirty handlebar switch.

Take the lens cover off & measure for voltage, check the bullet connector for that side assuming the bulb is good?

Yes, the bulb is fine. Tried to switch with the others, it works.

I haven't checked actually. Just been focusing on the left/back one. Will check!

The bulb is good - I'll try your suggestions, thanks.

If the wattage of the front and rear globes are not the same, the higher wattage globe will not glow.

Also check the wiring loom at the rear where it passes under the seat near the frame, damage can occur here.

Succes!!! I went through all the wires last night and finally found two errors. One of the bullet connectors was broken AND the socket for the bulb wasn't clean any more resulting in too low current to the bulb. The two things put together made the error. Fixing the bullet connector AND cleaning the socket with some fine sandpaper made the trick!

Thanks for the help and suggestions
