car is a 1997 Cadillac Seville Sts. My car started slowly losing power. It started with the lights dimming in and out and then I noticed when I would be driving the volts would jump between 11-14 volts and then it stopped doing that and just slowly died and now the car has no electric at all. I've had the starter replaced, the alternator, and battery replaced. No corrosion on cables wigggling the cables does nothing. When I try to jump the car the lights come on and car just makes rapid click noise and electric goes away when cables are taken off. What could be the problem??? Also fuses are fine...
