Gen water temp guage fuse

[iwander_85pt40]

Engine cold, sending unit wire disconnected: 12 volts thru a
voltmeter->wire to ground; no resistance->sender terminal to ground;
guage pegs far right when terminal wire grounded.

Engine at operating temperature (half hour+ run), sending unit wire
disconnected: no voltage thru voltmeter (wire was connected to
sending unit during warmup); no resistance->sender terminal to ground;
guage does not move when terminal wire grounded.

There is a jumper wire from the oil pressure guage to water temp guage
that I assume is 12 volts(I haven't tested it). The oil pressure
guage operation is normal.
