Possible wiring problem?

[noobpolice]

Hi, recently my Tach, fuel gauge, and temp gauge went out while i was rallying my car. since then i've noticed that the heater fan wont kick on. Now both my reverse lights dont come on either. On top of that when i first start my car sometimes my battery light will be on and my sub wont sound good till i rev the engine up a little, at which point the sub sounds fine and the battery light disappears.. I bought the car a couple months ago and the only problem it had then was the digital computer didnt function normally(which i would love to fix). The car DOES read 360,000mi but it was owned by a bmw mechanic who donated my old totaled e30 into this one. I replaced a blown fuse but that fuse blew out soon as i started the car. Any ideas whats going on? Where can I start? Looking to fix all these problems asap. Thanks!

I have double posted this (one here the other at the electrical forum) because i need people to see it. Sorry but thanks!

A fuse blowing suggests a short in that circuit. You'll have to trouble shoot that circuit to see where the problem is. Wiring diagrams can be found at http://wedophones.com/BMWManualsLead.htm
