Hello R3V, I need your help on a 91 4-door Automatic E30 that I recently purchased. This is my second E30.
Fuse #10 consistently blows every time key is turned to ON position, car cannot turn over or start.
Here's how it began: Was driving home when suddenly smoke started seeping through the dash. So I cut the motor and coasted into a parking lot, popped the hood, and found that Fuse #10 was nearly melted on one side. Popped in a new fuse and tried to turn the key to ON position, pop, fuse 10 blows.
After searching, found this thread with similar issue (all the other threads I found were referring to the reverse light wire for manual cars): http://bmwe30network.net/forums/read...5,11422,page=2
OP figured out it was a green/white wire running from instrument cluster through the firewall. He replaced the entire harness.
So far, the radio, instrument cluster, glove box, and all lower trim under dash are removed. I cannot see any single wire that looks shorted/melted/charred.
I'll be removing the fuse box or dash next up, but I had a few questions first.
My Questions:
1) Does the automatic E30 have a similar reverse light wire that runs near the driveshaft? I lifted the car and didn't notice any wire leading to/from gear shifter body hole.
2) Does anyone have any experience as to how and where exactly the main harness wire that includes the components for Fuse 10 runs through the firewall?
3) I should add that this car had an alarm. I removed it after this Fuse 10 issue started and reconnected the wires.
4) I also replaced the starter relay but that didn't help. I tested the starter motor and it turns fine, just like my other e30.
5) Other info... this is probably not related to Fuse 10... but while my car is unlocked and just sitting there, as soon as I open the rear left passenger door all the doors including the one opened lock automatically. It doesn't do this with any other doors besides that one. I already took off the trim and wire covers to locate a short, but the wires in the door look spotless.
Any suggestions, comments, and even guesses are welcome. I'm at a loss of ideas here and will be pulling off the fuse box and then the dash after. Most likely going to order an electrical circuit tester to see if that helps to find the short or problem.
