electric problem its a weird one

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

Re: electric problem its a weird one
 

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

so cheak that groung around the drivers side a piller and firewall?

Re: electric problem its a weird one
 

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

i found the problem it was the ground on the e brake 1 snip crimp ans a slip everything works like it should the ground looked good at first glance but the e brake wasnt tightened down and the bolts are rusted in place so i moved the ground thanks alot for the input
