ground issue

[matthufham]

my truck is tripping out. all the electronics refuse to work correctly when they functioned fine before the truck left for paint. i think it's a ground problem. some grounds i can name:

battery neg to engine head
pass inner fender to frame
firewall to rear of head on engine
front passenger cab mount on frame to cross sill on cab

i should think there's more than that, so if you guys can name more, thanks
