: 735i circuit board problem

12-15-2005, 08:37 PM
My 1988 735i has an electrical short in a circuit board located in the dash. About 0.4 amps are drawn continuously with the ignition and everything shut off, killing the battery. The fuel gauge does not work. Any tips how to get at and repair the board and are replacements available?
