Left signal light problem--NEED HELP!

[cromwell1234]

Well almost got killed turning left today, discovered the left turn signal doesnt work, the front stays on (solid yellow) when I turn left but the rear does nothing, the bulb is good, what could be wrong----

LIghts

Did you swap them around to make certain it's good? (You probably did but that sure sounds like the problem....) You might also check for corrosion in the socket and on the bulb, itself.

I second the burned out bulb theory. I just spent several hours this weekend doing continuity tests all over my bike to troubleshoot a similar issue only to finally look again at the bulbs and determine they were burnt out. The reason I didn't identify them as burnt out to begin with is that I only looked at the curled portion of the filament (which was intact) and didn't scrutinize the straight portion, which is where the break was.

It is easy to buzz a light (with a ohm meter) or just put 12V to it and see if it is still intact.
The front comes on and doesn't flash because the flasher needs a certain amount of current (mini9mum required from two bulbs) to cause the flash to "flash". Since the rear light is off, that would prevent the front from flashing so it stays on and there is likely nothing wrong with it.

Do one of the definitive tests above and if the bulb is good (if not replace), then look for the ground path for that bulb that is not lit. As a etst run a seperate groudn wire to the non-lit light and see if that does it. I'm assuming you have 12V to the other leg when the blinker is on.

Should come to a solution pretty quickly.

Like said ,BE SURE the bulb is good. Check inside socket, sometimes water gets in there & rusts inside of socket. Under the seat there will be a plug that connects the signal to the harness, possibly one for ground also, depending on model.

Check your connections. I had a similar problem, found it to be the connector from the signal stem to the harness...they get a lot of water under there if you get caught in the rain...

Its a ground

If the bulb checks good it's probably a ground problem. Found this on my "T" model. Make sure the contacts are good on the socket, check the connectors at the signal, then check the connector that you'll probably find under the seat near the battery.
