I have a 78 Bronco and I received a boost from a older gentleman and he crossed the wires which made the dash go up in smoke. I havent traced back the wires from point to point but I seem to blow alternators?? Im not sure what could be causing the problem?? If anyone has any sugestions feel free. Im about to pull the truck into the garage to start pulling the dash and everyhting apart so like I said let me know and I will do my best.
