Circuit Breakers If you need to check a circuit breaker that is on the fuse panel, see Checking and replacing fuses in this chapter to find out how to locate the fuse panel. Circuit breakers will reset themselves and allow the electrical parts to work again once the overload on the circuit is removed. If the circuit breakers continue to cut off electricity, have your vehicle's electrical system checked. Diagnostic equipment is needed to check circuit breakers. Refer to the manufacturer's instructions. If you replace a circuit breaker, use one with the same amperage rating. To remove a circuit breaker mounted in the fuse panel, grip it with your finger and thumb and pull it straight out of its socket. Since the circuit breaker for the headlamps is mounted in the headlamp switch, you must replace the entire switch to install a new circuit breaker. Fuse Links Fuse links are circuit protectors that are part of the wiring harness for some electrical equipment. These, like fuses, open when the circuit lead exceeds their amperage rating. Fuse links may be purchased from your Ford or Lincoln-Mercury dealer. See the following charts to find out which electrical parts are protected by a fuse link. 184
