ammeter/bypass problems

That actually makes a lot more sense so do you think it can be a short along the ammeter wires causing the problem? I drove the car it worked fine with the way they were hooked up then nothing after that. No ignition no lights nothing. It gradually got worse it would pop the fuse once a week then daily then after every drive now it pops the moment I hook it up. And could anyone tell me where on this diagram the ammeter would be?
