you either have a ground problem or its picking up positive power from somewhere via a short or something is wired into it that shouldn't be

 

i dont know i look over the hole harness and theres nothing wrong with it.

 

still no help....................

 

can somebody help me out please.

 

Follow the Helms manual for troubleshooting. You'll need a multimeter.

Were you doing anything recently with the cluster or wiring that we should know about to help diagnose?

 

well the alternator fuse kept blowing up i would put a new in and it would do it again. so i took the harness of the motor and check it and there was nothing wrong with it so i put it back and as i was under the car while i had it on the lift i notice that the O2 sensor one of the wires was cut up by the heat shield. so every time that i wood turn the car on after i would put in a new fuse it would blow it. so i tape it up and the problem was over with but now that i put the harness back on the motor the fuel gauge stays on full and the speedometer stays shaking up and down on the 20 miles mark. so thats where im at.
