Wild voltage
I'm having trouble diagnosing a wild voltage problem with my 87 IROC.
When the brake pedal is depressed, the warning buzzer sounds, the instrument panel lights up, and the front marker lights come on. I replaced the brake switch, same results. The interior is stripped so I checked all of the grounds that I could find. The only ground not hooked up is the 3rd brake light.
Any suggestions?
Thanks!
