Diagnosis And Testing - Circuit Breaker

WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

For circuit descriptions and diagrams, refer to SYSTEM WIRING DIAGRAMS .

  1. Locate the correct circuit breaker in the junction block. Pull out the circuit breaker slightly, but be certain that the circuit breaker terminals still contact the terminals in the junction block 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 (PDC) as required.
