12-Volt Battery - Electronic Drains Which Shut Off When the Battery Cable is Disconnected Test

1. Repeat the steps of the 12-Volt Battery - Drain Test.

2. Make sure all doors are closed and accessories are off. Without starting the engine, turn the key to ON for a moment and then OFF. Wait a few minutes for the illuminated entry lamps to turn off, if equipped.

3. Connect the ammeter and read the amperage draw.

The current reading (current drain) should be less than 50 mA (0.050 amp). If the current drain exceeds 50 mA (0.050 amp) after a few minutes, and if this drain did not show in previous tests, the drain is most likely caused by an inoperative electronic component. As in previous tests, remove the fuses from the BJB and the SJB one at a time to locate the problem circuit.
