Right Rear Turn Signal Problem

[MTime]

Ideas - Right rear turn signal stopped working on my '01 1200 Custom. I have

-Replaced bulb
-Checked harness
-Checked Fuse

If I swap the L/R plugs in the tailight module, the right rear turn light WILL work when I press the left turn signal button. So I'm thinking it is something other that wiring or fuse.

Help????

Have anything extra in the ckt. such as a module to convert the turn signals to running lights?

If so, take it out and see if it changes things.

I had a add-on Kuryakyn Turn Signal controler on my bike, wires got shorted then the harness fell against the tire. Repaired the wiring but I couldn't get the light to work, even though I had 12V battery and ground. I did the same thing, swapped the leads as you did and tbl stayed the same.
Funny, my problem was with the same rightside bulb.

It would not light a stock bulb but it would light a LED bulb. Had me scratching my head.

Then I remembered I had the module in the ckt. Took it out and lights started working. Smelled the module and it smelled like it was fried. Peeled back the insulation over the ckt. board and I could see where it got fried. Had to replace the board. Evidently the stock light was too much of a load to light but could still handle the LED bulb after the ckt. board got fried.

All you need is 12V battery and grd. to make the lights work. Make sure you have both.

Look at the wiring under the fender. If it comes loose and rubs
on the tire it will wear down real quick.

Yes - I've gone through the fender wiring completely. Under the seat there is a module that a deutsch connector goes into b/4 going to the back lights. Is that a possibility?

Yes, check it out with a good light and get the dirt off the wiring so you can see it well.

That was my original problem when the harness slipped out of the loom, hit the tire and wore through. Turn the wiring harness enough to see all sides. It doesn't take much of a rub to open the wiring.

It does come out of that connector but wouldn't think you'd have problems there. They seal them very well.

Checking my factory electrical manual, it comes down to possible open wires or defective turn signal module (TSM).
The book gives an involved tblshooting sequence.

Do you have 12V and grd at the rear light?

Also, you can swap a buddies turn signal module and see if the tbl clears? Both Sportsters and Dynas use the same TSM.

That means the right rear circuitry including the TSM is ok.

Did you check to see if the right TS switch operates the left TS lamp?

Maybe the problem is in the switch?

I will check the TS Module and the wiring again.

jwb - tried alternating the ts switch.....not the switch
