Thanks, Bill. Just what I needed.
Don't know why I didn't try to continuity check first. Of course, I did check and found 12.something volts across the two terminals. That 'should' indicate a good circuit, right?
Seems there's a fussy little foil layer between the back of the gauge and some insulators on the posts. Will have to make sure that's where it is supposed to be.
Out of curiosity, a bad sender would behave how? I read here that the test for the gauge was to ground the sending unit wire out to 'peg' the gauge. Is there a similar test for the sending unit?
And, finally, when the radiator core is buried, just, with water, can the sending unit be removed without draining down the coolant some?
Thanks again,
Jim
