I PULLED THE FUSES, USED THE TEST LIGHT IN BETWEEN THE NEG. BATTERY POST AND NEG. BATTERY TERMINAL. I STILL HAVE A BATTERY DRAIN WITH ALL THE FUSES OUT AND THE DOOR CLOSED. I UNPLUGGED THE ALTERNATOR, CONTINUES TO DRAIN A FULL 12 VOLT DRAIN.

Hi there,

Thank you for the donation,

You are on the right track with this test but it should be done with an Amp meter, with the ignition off and doors closed you will want only around.1-.15 Amps current draw, this is the stay alive current required for system memory retention, a test light will show only current and not Amps being drawn, do the test with the Amp meter and see what you get and report back.
