Water temp gauge works (reads resistance) until it hits 150, but as temp continues to increase, it goes to 0. Pick up speed and once engine temp drops the gauge starts working, but it will only read below 150 deg.
I have a 160 deg thermostat, so the temp reading of the gauge with the engine running is not accurate.
If I shut the engine off and turn the ignition to "ON" the temp gauge works and reads accurately above 150 as tested with an infra red temp tester.
I've replaced the gauge and the sender, but still have the same problem.
Sender is grounded metal on metal.
I've run a wire directly from the sender to the gauge but still, same problem.
What am I missing here??
