Topic: Gas gauge pegged at Full

[BlkBird]

A ground wire off? Its more then likely that, back at the tank, correct? Im not big on electrical stuff...though with this car I will be before its all over

Hey Mike, just went through it with the Pace Car... ground it was, at the tank... little electrical connectro broke off... easy fix, new connector, drilled small hole in the rear valance and connected it back up... works great now...

Thanks, that's what I was figuring. Im going to check that out asap.

[MikeW]

Hey Mike, did you get around to checking the ground wire? Just curious.

Nah. My car is over at my bro-in-laws so I just cant "run out to the garage" or anything to check it. Its a 20 minute drive just to get there. Im heading out that way tomorrow though so I'll probably check it out then.

my car daytona 500 edition has the fuel gauge pegged past the F/Full mark as well. Is that a ground bad ground or bad sending unit?

[BlkBird]

I BELIEVE that means your ground wire has broken off (apparently pretty common) that's the black wire that comes over the top of the tank to a screw mounted on the tail panel with an internal toothed washer.  If that connection is missing/bad the sending unit won't work.  If that connection is there and is good, then the sending unit is likely bad.

I have a 1983 Daytona 500 edition where would this ground wire be located do yuou hav any photos or diagrahams

[BlkBird]

Oh, I was'nt thinking 3rd gen. Im not sure where the wire would be located, or if the statement I made would even be true on a 3rd gen, sorry.

Ground is probably at the tank on that in the sending unit (ya are having issues there already? Maybe ya will kill 2 birds with one stone!

[gauge_marks]

Any time a fuel gauge pegs past full, it means that the gauge has lost the resistance to ground from the sending unit. Like others have said, it is most likely the sending unit ground. Other possibilities are a bad sender, a bad connection to the printed circuit on back of the gauge cluster, or a bad printed circuit.
