    E12 help

    I recently purchased my first BMW a 1980 528I and after working through the more obvious problems I am now trying to address some of the electrical problems. Does any one have any experience working with this particular model, or have any suggestions for how to fix the following problems?

    car will not start at normal starting position (i.e the end of the key barrel turn). instead it starts randomly between 60-80% of the barrel turn.

    Previous owners tried to rewire for sound and did a terrible job. Do I have to pull off the dash to access all the wiring connected to the instrument cluster and radio? I ask because I think at this point the car audio is beyond repair and should just be removed, also the dash lights are dead.

    I realize this is probably related to the crappy car audio job, but the battery dies almost over night. Does anyone have a suggestion as to how to get that to stop.

    2 of the 4 electric windows are missing motors and controllers. does anyone have a suggestion for getting these windows working again.

    I hope to hear from someone soon, id like to get this thing back on the road soon!
