Aerostar 2WD V6-3.0L VIN U (1997)
Circuit Breaker: Testing and Inspection
NOTE: Front wiper motor and washer motor use the same circuit breaker.
The six-amp circuit breaker is located in the fuse panel.
Two separate tests are necessary to check for correct circuit breaker operation. Remove the circuit breaker from the fuse junction panel and connect the
tester leads to the circuit breaker.
Test 1
1. Before connecting the circuit breaker to the Alternator, Regulator, Battery, and Starter Tester (ARBST) 010-00725 or equivalent, short the
tester leads together and adjust the current draw until it equals the circuit breaker rating.
2. Connect the breaker to the tester. Leave the breaker connected to the tester for ten minutes. Hold the current reading on the ammeter at the
rated current. If the circuit breaker opens during the ten minutes, replace the circuit breaker.
Test 2
1. Short the tester leads together and adjust the current draw until it is twice the rated current.
2. Connect the breaker. Hold the current reading on the ammeter at twice the rated current.
The current reading on the ammeter should drop to zero within 30 seconds. If it takes longer than 30 seconds for the circuit breaker to open
(current reading drops to zero), replace the circuit breaker.
