Testing a circuit breaker

Note: If the breaker is tripped (white button is extended), press the reset button
of the breaker. If it does not reset smoothly, the breaker has failed and must be
replaced.

1. With the breaker reset, unplug the Logic, either at the wall, or at the power

cord inlet at the back of the electronics module, as shown in Figure 9-2.

2. Remove the two 7/16-inch acorn nuts and lock washers that secure the

module.

3. Tip the module on its side to access the breakers.
4. Using a continuity meter, check the continuity (resistance) across the

terminals of the breaker being tested.

5. The resistance across the breaker should not exceed the resistance noted

when the meter probes are connected to each other.
