With Clamp on DC Ammeter Test Procedure

1. Turn the ignition switch OFF and make sure there are no electrical loads. After determining that the engine compartment lamp is turning off properly, disconnect the lamp.
2. The current reading (current drain) should be less than 0.05 amp. A current drain greater than 0.05 amp indicates a constant current drain which could cause a discharged battery.

If the drain is not caused by a vehicle lamp, remove the fuses one at a time until the cause of the drain is located. If drain is still undetermined, disconnect leads at starter relay one at a time to find the problem circuit.

NOTE: Do not start vehicle with clip on cable. Clamp the meter clip securely around positive or negative battery cable (all cables if two or more lead to post).
