2013 Fx4 F150 Parasitic draw
Hi there,
My truck has a parasitic draw that I can’t track down. I’ve put a multimeter on it and pulled every single fuse and relay and I can’t get the draw to drop. (It’s around 2.5 amps.)
Any thoughts? I’d really rather not sell my soul to the dealership to have them throw parts at the problem.
Thanks!

My next suspect would be the alternator. I'm thinkingyou have a bad diode. Feel the back of the alternator when the truck is cold and see if there is any detectable warmth.
