Isolate battery drain - normal draw?
I'm trying to isolate a minor battery drain on my 2002 King Ranch w/5.4L.
What would be considered a "normal" battery drain on the ammeter with the underhood bulb dis-connected and the truck shut off for 1 hour.?
Right now, I'm getting .26A between the neg battery post and cable.
Thanks!....

I recently checked out the battery drain on my 2001 excursion with 5.4L engine. When I first connected my ammeter it read close to 400mA. After a few minutes it dropped to about 250mA, with a little spike of a few mA every second or so. I assumed the spike was caused by the instrument panel theft light blinking on and off. I left my meter connected all night long. The next morning the ammeter was bouncing between 13mA and 16mA, once again, presumably because of the anti theft light.
