'70 C10 Temp Gauge Max Hot, Why? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

1970 C10, 402 engine, with gauges. Temp gauge was max cold when I got the truck last summer.

I put in a new temp sensor, new OEM temp gauge, new instrument panel bulbs and bulb holders, and new instrument panel printed circuit board. Now temp is always max hot. I did continuity check on wire from temp sensor to passenger-side post on temp gauge and it checked good. Got 12V on drivers side post of temp gauge.

I'm stumped. Any ideas?
