Well I did the advised test to see if the water temp gauge is dead or the sending unit and when I hooked the temp gauge wire to the battery ground and turned the key,nothing! The gauge did not peg out. I suppose without pulling the gauges and testing directly I might be just chasing my tail. Any other checks would be appreciated. Thanks!

el System.” Group 14.
Temperature Gauge
Disconnect the terminal from the temperature
sending unit on the engine. Connect one test lead of
tester C-3826 to the terminal and the other test lead
to a good ground. Place the pointer of the gauge
tester on the ”L” position and turn the ignition switch
to “on.” The temperature gauge should show “C” plus
or minus 1/8 inch. Thermal gauges are slow in operation. Allow time for gauge to heat up.
Place the pointer of the tester on the “M” position
and the temperature gauge should advance to the
driving range or 1/2 position of the dial. Place the
pointer of the tester in the ”H” position and the
gauge should advance to the “H” position of the dial.
Should the gauge respond to the above tests but not
operate when the terminal is attached to the sending
unit, indications are of a defective sending unit and it
should be replaced.
Should the gauge fail to respond to the above tests,
indications are of possible loose connections, broken
wire, open printed circuit, or faulty gauge. The instrument cluster should be removed for further in

Does fuel gauge work? Back up to next connector. Undo at bulkhead and ground sensor wire.
