Circuit Breaker
Slightly pull out circuit breaker No. 1 (20-amp) in junction block, but do not remove. Ensure circuit breaker terminals remain in contact with terminals in junction block. Check voltage at both terminals of circuit breaker. If battery voltage does not exist at either side of circuit breaker, repair power distribution circuit as necessary. See appropriate wiring diagram in POWER DISTRIBUTION article in WIRING DIAGRAMS. If battery voltage only exists at one side of circuit breaker, replace circuit breaker. If battery voltage exists at both sides of circuit breaker, circuit breaker is okay at this time.
