Current draw question
Recently my 02 F250 starting getting very hard to start. I've got 2 optima yellow tops in it and after a night of sitting it's slow to start and after 4-5 days it needs a jump. I did a current draw test and found something was pulling 3A with the key off. I started pulling fuses and when I removed #19 (Body security module / 4X4 module) the current draw dropped to only a few milliamps. Interestingly enough, if I put fuse #19 back in and pull fuse #35 (Instrument cluster) the current draw goes away as well. So, if I pull either fuse, the current draw goes away.
Has anybody else had his problem? The fuses never blow so I know nothing is shorting. I'm pretty sure I've got a bad part somewhere I just don't know what part.
Thanks, in advance, for any ideas or assistance.
