1989 Cadillac Brougham V8 Two Wheel Drive Automatic
Ignition in general is the problem. Probably the switch as you said. How do I test the switch? Today I hooked a different battery up. On accessory, the car had full power. As soon as I turned the key to start, the positive batt. Terminal sparked and the batt. Was completely dead. Just a little more info for you. I was wondering if you could tell me why the switch works fine when hooked to jumper cables but not when it tries to start on it's own. Please don't take offense, I'm not questioning your answer. I just don't understand. Ignition wiring is definitely not my strong point.
