PostSubject: Turn Signal help   Thu Jan 26, 2017 6:55 am

Hey all,

So I finally got clearance from the arm surgeon to start riding again (yay), so I decided to swap the bars on my GRiSO out, and I appear to have fixed it until it broke (boo). The swap seemed to go smoothly enough and I didn't have to unplug anything and even got heated grips installed. Now everything works fine except the right front turn signal. Left turn signal works, except it's pulsing very quickly, and the right rear turn signal works, but nothing from the front right. I swapped bulbs with the same result so it's not that. And the dash is displaying a very helpful symbol telling me that the right turn signal isn't working. Anyone have any suggestions?

Thanks!

Caleb

Most likely one of two things. Either the connectors of the non functioning indicators to the loom have been separated or simply moved enough to break the circuit or the wires to the bulb holder in the indicator itself have pulled off.

Getting to the rear connectors is a bit of a pain as they are right up in the arse end of the tail section, front ones are much easier but you'll probably have to pop the tank off.

Check the bulb first.

Papa - I swapped the bulb first thing to check with the same result (that's about the only mechanical skill in my skillset =)

Pete - Thanks for the advice. I'll tear into it some more this weekend and see if I can trace the wires from the front right to see if they got pulled somewhere.

IIRC the front signal connectors are up inside the instrument housing. You have to pull the dash off. Most annoying.

I thought they were behind the steering head but I haven't had to mess with indicators for ages so I can't remember! Razz

On most bikes the turn signals work off each other on one side. I would expect one to be flashing faster than the other only to be connected to the same side-ie, if the front left hand bulb is flashing too fast, then the rear left hand bulb isn't working.

Mebbe MG is different but I doubt it.

While the system still works that way the indicators on our bikes are controlled by the dashboard and there is logic in there that causes the rapid flashing if an indicator not working. In this situation it is almost certainly a loose or disconnected connector if the globe isn't shot, (You have stuck a mm across it? The filament can look fine and it can still be OC.)

Thanks so much for all the help guys! I found the issue late last night after much swearing.

While I was tracing the wire back from the turn signal stalk up to the dash, I noticed a pretty tight kink in the rubber sheath directly behind the headlight and when I peeled the sheath back once of the two wires was crimped nearly through. Put a quick butt connector on there to test and it worked. Going to solder and heat shrink it this weekend.

I really appreciate everyone's help. You really are the most helpful forum I've ever found.
