Circuit Breaker Test
- Locate circuit breaker in fuse block module. Pull out slightly, but ensure circuit breaker terminals still contact terminals in fuse block module.
- Connect ground wire of voltmeter to good ground. With probe of voltmeter positive lead, check both terminals of circuit breaker for battery voltage. If only one terminal shows battery voltage, circuit breaker is defective and must be replaced.
- If neither terminal shows battery voltage, check for an open or shorted circuit to circuit breaker. Service and repair as necessary, and test components.
