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

WARNING: This page is about a different car, the 2004 Ford RV Cutaway, 2004 Ford Econoline, 2004 Ford E450 Super Duty, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
  1. Repeat the steps of the battery drain testing.
  2. Make sure all the doors are closed and accessories are off. Without starting the engine, turn the key to the ON position 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 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 a malfunctioning electronic component. As in previous tests, remove the fuses from the fuse junction panel one at a time to locate the problem circuit.
