Do you have jumper cables? If so, you can use them to bypass your ground wire. Take the negative battery cable off of the battery. Hook one end of the jumper cwble to the negative battery post. Now hook the other end of the jumper cable to the engine (a good place is the hook used for pulling the engine, right next to the alternator). Still no power? Move the jumper cable from the hook to a bolt on the body of the car. If you still have no power after this, then the negative battery cable is most likely NOT the problem.

To diagnose further, you really need to get a multimeter, or at least a test light. Without the proper tools, nobody here will be able to help you.

Soo if I hook the jumper cables to the battery and to the ground on my car and get power its the ground? Your saying
