Headlight and Taillight Warning Indicators

[fast eddie 52]

are coming on at random, with no problems in the operation of headlite and taillite, 1st noticed this on my '82 GS1100e that has 80k on it, now is showing up on my '83 GS1100e with 34k on it, and my son's '82 GS1100e that has <20k on it has done it a bit as well...what's up with this??? Is there a bulb moniter box needing replaced on all 3 bikes??? Didn't find anything in search, but this seems like an awfully common prob. if all 3 of our 1100e's are having this glitch...

Sounds like an intermittent grounding problem. Time to get the wiring diagram out and start tracing. If you are lucky it will be the same point for all the bikes.

I'm not getting any flickering of any of the lights being monitored, headlite, tailite, and stoplite all work flawlessly...yet the warning lights come on and stay on for random times...sometime just one, sometimes two at a time...I could start cleaning all the ground connections, I'm more inclined to think some black box is just flakeing out with age...

As you wish. Did you check the wiring diagram to see the source that particular bulb is connected to? It is all there if you take the time to look.

yeah, I'll do that, and while I'm in the schematics, I'll look for the bulb monitor circuit and just what that part is called...So you haven't heard of problems with the bulb monitor???

Same thing here on my 1100E...just the taillight, though...
I've tried different things with no luck, so I just ignore it. Someday I may pull the bulb in the cluster...

I noticed in the wiring diagram, there's a "control unit" for the panel indicators...anyone have to replace this unit to cure the false indications on the idiot lite panel???

Did a search and found this thread. My 83 GS1100E is doing this. Red lights going on and off at random. Has anyone found a common cause?

I changed the control box on my 83 GS1100E and seen no difference clean the grounds and check the plugs clean any and all wire ends and go from there
