Electronic Drains Which Shut Off When Battery Is Disconnected

1. Repeat the steps of the battery drain testing. [1][2]Drain Test
2. Make sure all doors are closed and accessories are off. Without starting the engine, turn the ignition switch to RUN 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 0.05 amp. If the current drain exceeds 0.05 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 fuse junction panel one at a time to locate the problem circuit.
