Yes, check the ground..

Hey TSPS,

Your avatar has me thinking of work because I know exactly where that is, been through there many a time.

I spent a few months down there when I was still shipping , the white ship is the Patriot State ( Santa Mercades ) when Grace Lines owned her .

Absolutlely, check the ground first. Just about every time I have an issue it's the ground. Most recently, I solved my issue by drilling a new hole in my vehicle frame and using a new screw to attach the ground wire to the new hole. Problem solved, rust had accumulated between the screw and the frame.

Good luck!

get a new length of wire (12 feet long) with a hefty aligater clip on both ends

so you can isolate individual wires and by pass the old to see whats what.

I just clipped all my wires and re fastened them working GREAT!!!!!!!!
I was having ground problems ( lights dim and flickering) Try to use heat shrink fittings and dielectric grease
