i think you should also check the grounds on the wiring harnesses... ive seen a bad ground do that kind of thing

Electricity is lazy and will find the easiest path to ground. If you have a bad ground it will find another way out.

Thats a good place to start but it wouldnt hurt to spend some time and clean them all up ( there ain't many

) If this ones giving you fits others are close behind.

well i spent all weekend pulling out the 350 and put my baby under the hood and with that i pulled all the wireing from the firetruck days out i noticed the ground from the block to the firewall was broke and replaced with a wire and a selftapping screw maybe putting that back but better lol would help because the only grounds i have on the battery are to the block, core support, and the frame
