just got my LTx swap fired in my 87 trans am,and my tachometer and fuel gauge are not working and my radio is flashing like its being shorted out,also the volt gauge is reading very low.When i put the dome light switch on it seems to give a lil more power and im able to use my radio again and as soon as the dome light switch goes off the radio shuts off...WTF is going on??? its driving me nuts...i had a member on here build me the swap harness and im assuming thats not the issue but i do not know.before the swap everything worked just as it should.ive only taken the cluster out from the dash,everything else remained untouched.

Any help would be greatly appreciated!

anyone..

 

Wow that really funky, im just going to throw this out there but i have seen bad grounds do some really weird things like that. Dunno if it will help you or not but id check em out.

 

yeah actually i have checked all the under hood grounds but ive found nothing..i guess ill have to search more in the interior

 

also noticed today that gas gauge moves up the slightest bit if i put the dome light on...anyone know where the gauges main power feed comes from? what color the wire is?

 

Today i pulled the Cd player out and unplugged it to see if it had anything to do with the gauges not working and now when i start the car it all the gauges work (except fuel gauge still) and they all work even when the doors closed when they would normally all go out but as soon as i put the dome light on or parking lights they all go out...im hoping someone has some idea of whats going on? help would be awesome.
