Find and correct the problem that causes the circuit breaker to open. This will help prevent damage to the circuit components from too much current.
The circuit breaker is designed to operate in a temperature range of −40 to 85 °C (−40 to 185 °F). Because the circuit breaker uses an electromagnet rather than a metal element that responds to heat, the circuit breaker is not affected by changes in the ambient temperature. Also, the electromagnet operates faster than a metal element.The circuit breaker is reset with a toggle switch. If the current continues to exceed the circuit breaker's rating, the electrical circuit will remain open even when the toggle switch is held in the ON position.The power distribution box has four circuit breakers that are identified in Illustration 1.

The power distribution box is located on left side of the engine.
(1) Power distribution box
(2) 2.5 amp circuit breaker for the engine control
(3) 10 amp circuit breaker for the customer
(4) 35 amp circuit breaker for the engine
(5) 2.5 amp circuit breaker for the start command from the master ECM
(6) Positive terminal for the connection of the engine's power supply
(7) Negative terminal for the connection of the engine's power supply
