Circuit Breaker Test
- Loosen 20-amp circuit breaker No. 18 in junction block, but DO NOT remove. Ensure circuit breaker terminals remain in contact with terminals in junction block. Connect negative voltmeter lead to a good ground.
- Using positive voltmeter lead, check for battery voltage at both circuit breaker terminals. If battery voltage exists at both terminals, circuit breaker is good. If battery voltage exists at only one terminal, replace circuit breaker. If battery voltage does not exist at either terminal, repair open or shorted circuit to circuit breaker.
