I almost lost my 67 Camaro to a fire this weekend. I was driving it down the road when it started to hesitate and lose power. When I stepped on the gas it would accelerate and then backfire. To make a long story short. I lost all power to the car and had it towed to a garage. To my amazement the engine harness from the coil to the distributor, to the starter was completly fried!!!!
When they pulled the harness off the car, every time it back fired it blow a piece of wire apart and melted the harness. They said I was lucky I did not have a fire. Needless to say. I am in the process of ordering all new harnesses for the car. What it looks like happened was at some time in the past, someone spliced into the starter cable to make it longer. The electric tape around this splice came loose and the wire started to short out against the starter. Lesson for today,,,,,,,,,,,,,make sure you check the harnesses of the car and see what kind of shape they are in also when you thinking of buying older car.
