My mistake, sorry.  Rob, your trouble isn't in the gauge.  It's
either the controller itself or a contact problem of some sort
including sender pins that could have conductive trouble even if they
look reasonably clean.  If shorting the harness at the sender fixes
it, that's no doubt the trouble.  Clean with very fine sandpaper or replace.

Yours,
