OK, please realize I have little understanding of electricity. Here is the problem. I have the Flex-a-lite fan with thermostat. I also have an override switch. When the car is running at temp with the override switch off, one of the ignition wires gets hot as hell. When the overide switch is flipped on, the wire cools back down. Whats going on here? I can tell that this wire burned out and has been replaced before. Something is causing an overload. Maybe a better question is: what is the proper way to wire this set-up? Do I need a relay?
