Circuit Breaker

Locate correct circuit breaker in fuseblock module. Pull out slightly, but be sure that circuit breaker terminals still contact terminals in fuseblock module. Turn ignition switch to RUN position. Connect ground wire of voltmeter to a good ground. With probe of voltmeter positive lead, check both terminals of circuit breaker for battery voltage. If only one terminal has battery voltage, circuit breaker is faulty and must be replaced. If neither terminal has battery voltage, repair circuit from ignition switch as required.
