Operation CHARM: Car repair manuals for everyone.

General Information

All electrical circuits are protected against excessive loads which might occur because of shorts or overloads in the wiring system. Such protection is provided by a fuse or circuit breaker. A short may cause a fuse to blow or a circuit breaker to open.

IMPORTANT: After any electrical repair is made, always test the circuit by operating the devices in the circuit. This confirms not only that the repair is correct, but also that the cause of the complaint was correctly identified.
