odd electrical problem

[mosportgreen66]

Hey Guys,

Today the OBC stopped working, as did the radio, interior lights and trunk lights, even the heater/ac control lights stopped work as well.

First thing I checked were the fuses. To my surprise, they all look to be in fine working order, not broken. I may replace the fuses regardless as they're 2.5 years old, but regardless, is there any e28 specific quark I should check or investigate?

Any help would be great!

Check, retension contacts on fuses 5,6 and 12. If that doesnt work, take apart, clean ad tighten, the connections on the battery terminal. If that doesnt work, clean and tighten G200

A, thanks a lot buddy!

What is a G200 though?

one of the main grounding points, located behind the drivers side knee plate near the steering column. It is one bolt that accomodates many wires and grounds them to the chassis.

Could you supply a reference photo? Thanks.

I've have good results using nylon ties on the fuses:

How much you wanna bet its not G200, but qa loose fuse contact or broken fuse...

I'm chasing an electrical gremlin so as my first step I'm eliminating ground issues. After squirming around under my steering column for forever I searched "G200 location" and immediately found this:

What an incredible resource is this forum. In 30 seconds it directed me (once again) to Mr. Paine's magnificent site. Thank you beemters and thank you Rod.

(my gremlin: when I hit the left turn signal my interior gong goes off and the lights don't blink!? Just started doing this last week after putting about 5000 miles on this 'new' 535is.

Any ideas?)

in google search "bmw we do phones manual" and then click on your year and model bmw and then look under power distribution to see which fuse powers those features. if it doesn't "look" broken, it may still be broken. gotta pull the fuse out and actually look at it.

[pleasefixitup]

check fuse 6. then check back here.

excuse me, completely mis-read this. the gong is for when the outside temperature hits freezing (or just above, I forget) that is interesting.... now I feel like reading.

ok - the "chime module" is at splice 207 or s207 in the schematic. I would also check your c219 connection.

the turn signals are grounded at g102 which is on the drivers side behind the headlights. there has to be something else, I just can't find it yet.
