[AT] How to test a fuel gauge/Sender??

[rdhaskell at juno.com]

Hi John.
Disconnect the lead from the sending unit.  With the key on, alternately
ground the lead, then have it open.  The gauge should go full scale
deflection from full to empty,or empty to full I don't remember which, if
it is working.
