id stop by your local ford dealership and have them look it up for you.

if i had to guess, i would say around 10mA.

on newer rigs, it takes a good 5 minutes or so for the amperage to drop after all the doors have been shut and everything turned off. im not sure if older rigs like ours have any kind of delays in the PCM or anything, but i would try waiting to see if the amperage drops just to be safe.
 
im like sucken like .440 amps so i started ullen fuses at the main pannel under the hood and 40 amp headlamp one was responcable for like .335 amps and the other 40a elect shift was pullin the remaining
 
hmm, that .335A headlight draw doesnt seem right to me. what all is on that circuit besides the headlights?
 
if none of the extra lights are on, i would start checking out your main light switch and multifunction switch as those are notorious weak links in older fords. i had the multifuntion switch melt down in one of my escorts and it caused some very interesting light functions.
