Thread: light problem

Started 1 month, 2 weeks ago by allguitar
Hi All, I'm pretty inexperienced with repairing electrical issues. I was wondering if anyone could please give me some tips on this one. I have a 2001 XL1200S. Recently the right blinker flutters on and off, when the blinker is not activated. So the front right yellow light gets brighter off and on, and at the exact same time, the rear blinker goes on as well. Also, at the same exact ...

Intermittent electrical problems are the hardest to pinpoint.Before you drive yourself crazy try changing the front bulb.The vibration over time can stretch the filaments without blowing the bulb and the running light can come into contact with the signal causing the blinking that you describe. Try this and if it doesnt work you will have to check the pigtail then work your way back.

Who knows, you may also want to try removing all the bulbs and cleaning the sockets with a new Green Scotch Brite pad. Cut a length off the pad and chuck it in an electric hand drill. Shove the other end in the light socket and give it a buzz. Clean the prongs on the bulbs also. Then give it a shot of CRC 2-26 You may get lucky.

I'd inspect the wiring between the right handgrip and the TSM. It sounds very much like the button is essentially being pressed for you.

Try a little dielectric grease on the contacts of the new bulb makes a water resistant contact I use it on all electrical connections on my bikes and my wifes car

Keep things simple, is there a condition, i.e. hot or cold or mechanical (tap with the handle of screwdriver), the handlebar area and if you have the seat off, the fuse area (likely corrosion there) and wiring harness areas for chafing. Once you find the area, go to the cleaning and protective troubleshooting phase and you will be good to go. The key here is, with an intermittant problem, ...

Good point . My dad a retired mechanic always said start at the source and work backwards and with electrical problems always check your grounds with out a good and clean constant ground u will have problems , Jack

Am I the only one reading where he said the problem is the turn signal activates all on its own? This doesn't sound like a ground or bulb connection to me. Check the wires between the turn signal switch and the module they connect to. Somehow it's as if he's pressing the button when he's not. It's either the switch itself or its wiring creating the circuit and initiating the signals. This ...

oops it does sound like a dead short in the wiring check between the switch and the light carefully with a test light

The possibility of a swinging filament in one of the bulbs is a very good possibility as mentioned above. If a swinging filament contacts the other filament in the bulb the power will be transferred into the other circuit and light the rear light as mentioned above by the OP. Also a short in the wiring between these circuits is a possibility also. The biggest problem comes from over thinking...

Glens you were Right! It does sound like a Bad Switch. Looks like I owe you $20. The $10 you gave me plus the $10 I owe you!

I'd think by now you'd be posting with information about what it was that was wrong. Disconnect the switch and see if it still happens. Find the next connector inline and try that next 'til you get to the module that's overseeing things. If the symptoms don't stop anywhere along the way it'd likely be the module itself with a loose/faulty component. I'm pretty sure the fault's on the control signal side...

Hi all, OP here again. So, first off, thanks for all your posts on this subject. 1.) I checked all the bulbs, but they're all good to go. I traded the fronts bulbs from left to right, and also the back bulbs left to right, but the problem remained on the right side in all conditions. Bummer, now I know it's more complicated. 2.) So, I'm attacking the right blinker switch, and I'm following the manual now. I took apart the...
