View Full Version : Fuses??
04-20-2008, 10:42 PM
My Beemer (1988 R100RS) has a problem with the running/plate lamp. Light works (tested it), but does not work. I traced the wiring, and wow! is all I can say. Anyway, I called up a BMW shop, and they told me the fuses are under the tank. I don't see a fuse box, and neither did a friend who was helping me with some other things on the bike.Repair manual says there is a box there as well. There are 3 relays next to each other. One is a light green color, one off white, and a gray one. Also, the light above the headlight stopped working as well.
Anyway, if anyone can help me out, I'd greatly appreciate it!:)

Problem above you got fixed. Let me give you a bump.
I'm understanding you that the bulb in the taillight is in working condition - not a bulb issue. I am also understanding that you have used a test light or volt meter and determined no voltage at the bulb contacts (dead citcuit).
I know that I had hell getting Suzi to take ground at the taillights. Riding compadres would tell me that they would be on and off while I rode. I made an "adjustment" to the grounding barrel and it's been fine for several months. If you have no voltage in the circuit - that is something else.
No collisions? Nobody digging around in there beyond looking to solve this problem?

I am going to go back to the dealer (useless as they are) with all the relays and ask them what they are for. I have an inkling I know which one it is. I'll Know by the end of the week.

Somethng more like circuit breakers than traditional tube or spade fuses?
Working on something close to this. Called the dealer and asked if they had a wiring diagram and they dont. Told me I had to bring it in to get it fixed.

You should not have to take an airhead to a dealer to find the fuses. I have a twin-shock R65, which is laid out differently than the mono-shock series, so I can't tell you where yours are, but on mono-shock bikes, they are NOT inside the headlight shell where they had been since 1970 (except for the R65 and the G/S series).
If you don't have an owners manual, get one while they are still available. Capital Cycle lists them.
