Posting for a buddy. He is in the tail end of a drivetrain swap and when he hooks up the battery all the dash lights blink/flash till he pulls the battery.. Help? I'll post a video and more details soon.
Alright finally had a chance to get on here I'm the buddy with the problem with my dash lights, checked all grounds under the hood looked for grounds in kick panels I'm at a loss for words as long as fuse number 1 is pulled no blinking of lights but comes back soon as you put it back help
I'm going to bet on a cut/damaged ground wire somehwere? ground strap from drivers side head to firewall maybe? alternator grounds to engine which should be grounded via battery negative post to timing cover.
