Barry was driving down I-95 when his radio died and the lights began dimming. He pulled off to the side and his wife noticed flames coming out the rear of the truck, setting the roadside on fire. They had the truck towed, a new alternator installed, and the truck has been fine since. But what caused the fire? Tom thinks it was coincidence. Ray thinks the failing alternator indirectly led to unburned gas getting into the exhaust system.
