Dash Blinks/flashes Constantly

[billison]

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.

Have all of the ground straps been installed?

 

[billison]

He's supposed to join and post soon.

So far he knows if he pulls the fuse it stops and it still does it without the relay.

He has stray voltage running around. Tell him he needs to go through and locate and connect all of his ground wires.

 

[billison]

Any suggestions on what grounds to check?

I would start with the battery, then alternator. Otherwise it could be a wire behind your dash. Just some ideas.

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.

Nope checked all those nothing wrong with any of em

Maybe something got shorted out or toasted. Sounds like it's time to tear down and put that fluke meter to work one wire at a time...
