<VV> Fuel gauge problem LM

[Charles Morgan]

Wayne, if you ground the sender wire, the gauge should read empty, not 
full.   Try grounding the tan wire directly at the gauge.  If the gauge 
reads correctly (with the ignition on), the wire between the gauge and 
sender is open (the open can be in one of the connectors).  If not, the 
gauge is bad.  You can test the donor gauge easily.  Ground the case and 
apply 12v to the terminal that the blk/ppl wire would go to.  The gauge 
should read well past full.  Perform the test again, but ground the 
terminal that the tan wire would normally go to.  The gauge should read 
empty.  (BTW, if the dash is not grounded well, the gas gauge will act 
funny, but so will all the dash lights.)
