Circuit breakers operate when a circuit overload exceeds its rated amperage. Once operated, they automatically reset after a certain period of time.

There are two kinds of circuit breaker, as previously mentioned, one type will reset itself. The second will not reset itself until the problem in the circuit has been repaired.

Circuit breakers are used to protect the various components of the electrical system, such as headlights and windshield wipers. The circuit breakers are located either in the control switch or mounted on or near the fuse panel.

If a circuit breaker has been tripped (overloaded) it may be reset as follows:

  1. Remove the circuit breaker in question.
  3. Unlock the stopper and pull out the circuit breaker.
  5. Insert a needle into the reset hole and push it in.
  7. Using a suitable ohmmeter, check to be sure that there is continuity on both sides of the circuit breaker.
  9. If there is no continuity, replace the circuit breaker.
  11. Assemble the circuit breaker in its case and install the circuit breaker.

If the circuit breaker continues to trip (cut out), a short circuit is indicated. The system must be checked and the short circuit repaired. Do not ever try to override the short circuit with a higher amp circuit breaker or replace the circuit breaker with a solid metal object. This would result in an electrical fire in the wiring harness involved in the line of that circuit breaker.
