When I turn the key to start my car, the voltage drops to like 8 volts and the car does not turn over or click or anything. It does not do this everytime, but is doing it a lot of the time. I realize there is a short because of the voltage drop as well as a white wire with a red or pink stripe that gets really hot. I know that a bad starter can cause a short, but I hear a clicking under the dash when this happens. So if the starter is causing the short, would something under the dash make any sounds? Or is there a relay switch of some kind under the dash that could be bad and causing the short?
