BRAT fuel sender problem, part 2

[Ever Victorious]

Ok... took apart the connector behind the right tail light and cleaned it out, and the problem has not changed or gone away: The gauge reads WAY too high. Currently, after having driven 100 miles on the tank, the gauge reads that the tank is 125% full. :-\

 

Next course of action?

Pegged out means the wireing is shorted to ground. Check the resistance of the sender by itself - if it's a dead short to ground then the sender is bad. If not then you have a short in the wireing somewhere. You'll have to trace it back to the gauge.

Just so you know;

 

There's 2 bullet connectors at the sending unit,

the connections behind the RH tail light,

another set of connections behind the front RH panel in the bed,

one more set of connections behind the B pillar trim,

more connections behind the RH kick panel,

then the connection at the dash unit itself.

 

If it is a shorted wire, you may be able to isolate what section it's in by working your way forward from the sending unit and un-plugging the harness at each point while checking the gauge. When it reads dead empty, you've isolated what section of the harness is shorted.

 

Sounds good in theory anyways.
