Electrical problem
1995 Cadillac El Dorado V8 Front Wheel Drive Automatic 185,00 miles
----------------------------------------------------------------
drove car to store, upon starting car to leave it made a popping noise, which we thought was the radio. We returned home and the next day the car had no power and would not start. I exchanged batteries and put in a good battery. The dome lights came on in the car. When I turned the key, I lost all power again.
I took out the battery and replaced it in the other car and iit started right off.
