Circuit Breaker: Testing and Inspection
For complete circuit descriptions and diagrams, refer to Wiring.
1. Locate the correct circuit breaker in the fuse- block. Pull out the circuit breaker slightly, but be certain that the circuit breaker terminals still
contact the terminals in the fuseblock cavities.
2. Connect the negative lead of a 12-volt DC voltmeter to a good ground.
3. With the voltmeter positive lead, check both terminals of the circuit breaker for battery voltage.
If only one terminal has battery voltage, the circuit breaker is faulty and must be replaced. If neither terminal has battery voltage, repair the open circuit
from the Power Distribution Center as required.
