Turn Signal Help 2001 Fat Boy

[BravesFan]

I am trying to figure out why my left turn signal and brake light work fine but my right turn signal wont work. I have checked the bulbs, sockets, wires, circuit board, and everything is fine. The only thing I have found is when I test the circuit board leads for each signal the one that works reads 11.6 volts, the one that doesnt work reads 9.6 volts. Could this cause the light not to work? If so, where do I go next? If not, any ideas????????

Do the hazard lights also not work?

[BravesFan]

No, neither one will flash with the hazards on. Both front ones do and the left rear will light as normal, but not flash, and nothing from right rear

Won't work at 906, you have a voltage drop somewhere. Did you change grips recently ? Or did you take the switch housings apart to lube the throttle cables ? Sounds like you have a pinched wire somewhere in the curcuit. You could also have a bad ground on one of he lamp sockets. Check for shorts and bad grounds, that seems to be where you problem is.

Of course it could be just a bad turn signal switch! :-P Just in case, here's some stuff to try:

Engine Light function: Normal operation=light comes on for four seconds after IGN SW on, then goes out if no present DTC. DTC in History=light comes on for four seconds after IGN SW on, then goes out, then comes on for eight seconds, then goes out. Current DTC=Engine light stays on after IGN SW on indicating current fault (note: some codes will only trip at engine run such as CKP)

The ECM is capable of displaying scanilyzer DTC's (diagnostic trouble codes). The scanilyzer is the diagnostic tool used at the dealer to troubleshoot the electrical system (similar to the digital technician for '03 and up bikes but less "versatile").

Speedometer Self Diagnostics: The speedometer is capable of displaying and clearing
speedometer, tachometer, TSM/TSSM and ICM/ECM Diagnostic Trouble Codes (DTC).
1- Turn Ignition switch to OFF & Run/Stop switch is to RUN {although my '01 XL will enter mode either way}.
2- Push odometer reset button in & hold while turning ignition switch to ON. Background lighting for the odometer should illuminate, speedometer needle MAY sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) MAY illuminate. "MAY" meaning not to worry if it doesn't but you will hear a "buzz" from the speedo in any case. The word “diag” should then appear.
4 - Push the odometer reset button once and you will see the selection menu "d01clr"
if no code is present or "d01" and a two-digit number for a code present such as "d0122" for the right turn signal for example.
5 - Write down on paper any codes then press and hold the odometer reset button to clear{*see NOTE2 below}.
6-Press odometer reset to go to "d02" and repeat. There is 11 different codes (d01-11) which do not correspond to any particular component; this is just a list of any codes stored. The two-digit code as described will correspond to a particular problem is all. A code for a particular component does not even necesarily mean the component is BAD but that further diagnosis is warranted. Diagnosis procedures will be listed in the Electrical Diagnosis Manual for the model/year of your bike. Last display will read "PPU" then a 5-digit number which I believe may be the ECM part number (but not 100% on this). In any case, this is not a DTC!
7-Any trouble codes present are as listed in Electrical Section of this Forum.

Thanks for both of you responding. I havent done any work on the grips or anything up front. I will give the things you suggested a try. Sounds like it is going to be one of those little gremlins hiding somwhere, finding it will be the challenge. Thanks again, I will post if I track it down.

Trade ya left for right side. I noticed on the wifes softail yesterday. Left side doesn't work or flash. Right side works well. Also noticed that when I turn the ignition on, not in run mode on the handlebar, the right turn signal flashes 6 times real fast. I will check for codes tomorrow. Just curious if you found the problem.
Thanks

Thou hast a current trouble code. Wow old post wonder how everything worked out...

[BravesFan]

I figured it out by taking it to the local HD shop.lol. It was a bad turn signal module(under the seat). Was about $125 bucks total. Thanks for all your suggestions, hope this helps.
