Hello everyone. I just purchased my first mustang to restore. It is a 1966 6 cyl. The previous owner tried to jump start the car and hooked the cables up backwards. As a result, the black-yellow wire running from the alternator to the starter relay is burnt up. I plan to test the alternator to see if its okay. If so, can I just replace the black-yellow wire and be fine or do I need to look at other areas for damage? I didn't see any other wires that were damaged. Thanks!!
