New mystery on my XJ1100

[gmups]

Ok, so here's another mystery ailment on my XJ1100. My brake light (Warning Lcd) stays lit. Check sensors & float on both M/C, both (sensors & float))good, brake fluid filled, brakes in good shape. Now the mystery, when I hit my "High Beam" switch to high beams it (BRK Lcd warning) goes out?? When I go back to low beams, it (BRK Lcd warning)comes back on. Any clues, my XJ/XS guru friends?? Thanks..

Any ideas, anyone??

Only I would come up with something no one else has experienced?? Any input as to where I should even start to look. I have an extra LCD assembly I got of ebay, didn't wanna swap, cause mine was in better looking condition.. may swap over just to see what I get.

Does the high beam indicator light come on when the high beam is lit? If not I would guess that the brake light indicator is actually the high beam indicator but reverse wired so it goes out in stead of on when the high beam is switched on. Check the block connectors for proper connection. Your going to need a wring diagram. I'm sure someone on the forum has one.

I don't know much about XJs, but is there a chance that warning light is multi-function? It may also indicate a burned-out headlight, so I'd check the headlight lamp to see if both filaments are good. If you have the same 'reserve lighting unit' as the XS, it will lower the output on the high beam if low is bad, and you may never notice the difference (except for the warning light )...

i was vaguely remembering the same thing,
maybe if the brake light wasnt working or doesnt the xj
have a battery fluid level sensor that could activate
the warning light?

I had the same problem with my XJ and found it to be in the level sensor in the front master cylinder. I bypassed it and just jumped the wire in the headlight that went to the cluster and grounded it. The level of the fluid is easy to see so I feel it really isn't needed.

Ok, so here what was the problem...

After taking my fairing off and going through a bee's nest of wiring left by PO, looking at the master cylinder sensor wires, they had the ground hooked up to the high beam (headlight) instead of to a ground!! I dug around and found the correct connections all fine now. Tidy up all the connections, used some shrink wrap and buttoned her all back up. Now all I gotta do is put fairing back on and wait for some good spring weather up here in NE Ohio! Thanks for the input guys, gave me a few ideas of how to narrow this gremlin down.
