Temperature Gauge don't work

Recommended Posts

My Temperature gauge doesn't work, there is power to the cluster, and good continuity from the sensor wire to the ground portion of the gauge. If I ground the sensor wire to the block the gauge only goes about 3/4 of the way to H. I took the cluster out of the truck and hooked a jumper cable to the hot terminal on the gauge and the sensing plug, the gauge pegged to H immediately, I then grounded the body of the gauge and it went back to C. Any idea what's going on here? I also have good continuity throughout the printed circuit.

I am having the same issue. Someone told me to make sure I have a sending unit for a gauge and not a light. I have not been able to check it yet but when I do I will post here if it made a difference.
