My 87 325is would not start because when I turn the key to 'accessory' or 'on' position, the voltage went from 12.4v to 9v. I tested individual circuit (green and purple wires) to try to find the short, by disconnecting ignition switch then jumper red and green/purple wires, but couldn't. I also did the 'load' test on the battery. Yes, I tried 2 different ignition switches with same results. Anybody got any idea what it is?
Thanks in advance.
