1988 BMW 325i Convertible Electrical Manual?

Question

I have a 1988 BMW 325i Convertible that seems to have some problems that I think are electrical. If these problems are indeed electical, where could I get a manual that contains wiring and electrical components with wiring/fuse diagrams? Would a "Chilton" manual have this? These are the problems. Lemme know what ya think.

1.) Driver Side Passenger window stuck in the open position. I'm not sure if it is the window open/close switch and wires, or if the window just came off the tracks.

2.) Turn Signal not working. Its in pieces. I need a new one.

3.) Rpm Tachometer doesnt show the RPMs. The needle stays at zero. I have no idea whats wrong here.

4.) Horn does not work

Any help would be greatly appreciated. I know nothing about electrical problems in cars.

You'll find the full electrical diagrams at the back pages of this repair manual.

A Chilton or Bentley repair manual would probably also have the same info.

To me it sounds like your alternator is bad.
start the car and remove the negative terminal,If egine stops,your alternator is confirm gone.
if engine does not die off,then go to a wreck yard/or salvage yard with your list and buy parts.
