Hey, Kid,

I agree with the guys who think you have a ground problem. I did away with all my ground problems by running a length of insulated 10 gauge single-strand housing wire (the stiff stuff that's cheap) all the way around the chassis. Everywhere I needed a ground I tapped into it, even running secondary grounds from it up into the cab. You can tape or put 'pookie' over the attachment points to prevent deterioration. Then forget about individual ground problems.
