HELP! Electrical Problem - 1999 323i

Hey Guys,

Sorta new here, looking for some help....

Bought a car at an auction today, brought it home and put it on the battery charger. Tried to start the car, wouldn't fire.... checked the fuses, 20A under the hood was blown, replaced and the car fired up.

So far so good.... about a minute later, some smoke came out from under the dash, near the drivers side, then the car died, and the instrument cluster, climate control, reverse lights, some other stuff won't turn off, nor will the car crank over.

When I say won't turn off, I mean I turn the car off, and pull the key from the ignition and these items remain on.

Any help would be great!

Sounds like some wires have burned and fused together. Disconnect the battery and start searching for that burnt smell. Maybe pull the instrument cluster out and see behind it. Also look at the back of the fuse panel and look for melted wires.

That is the best advice i can give with out more info and having my hands on the car. Get yourself a bentley manual that will help you out some.

If anyone has any ideas on how to help him or has had this problem before speak up.

Which fuse under the hood was blown? It would help to know which one. I suppose you're talking about one of the 5 fuses inside the e-box.

It was the 20A fuse, I don't recall what it was feeding.... however, when replaced it solved the fuel pump not operating problem.

Sorry I don't have the fuse chart handy at the moment.

Pretty much sums it up, pulled the dash (that was less than enjoyable).... there is a bunch of wires melted near the drivers side corner of the wiring loom.

It's a bummer, going to repair them and see what happens.

Well Mark one option is to buy a used wire loom for that side i did that for my old Range Rover (damn Lucas). It was easier and cheaper then buying new or separating and repairing all the burnt wires.

It's looking that way, took a better look at the harness... a number of wires (6 +/-) are pretty well melted from one end of the cabin to the other.

Not a good way to start off.....

Just to be sure, re-check your fuses again. Maybe the previous owner ran out of fuses (or got tired of fuses blowing) and just shorted them with thick wire. Unfortunately a lot of people do that thinking it would solve their electrical problems, not knowing they're worse off doing it.
