This greatly reduces thechance of fires caused by electrical problems. See "Fuses andCircuit Breakers" in the Index for more information. Headlights The headlight wiring is protected a circuit breaker in the light switch.An by electrical overload will cause the lights to go on and off, or in some cases to remain off. If this happens, have your headlight wiring checked right away. Windshield Wipers The windshield wiper motor is protected a circuit breaker and a fuse.
