Re: '70 C10 Temp Gauge Max Hot, Why?

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?

There are two senders for our trucks. One is for gauges and one is for lights. Are you sure you got the right one? I will see if I can find pictures of the difference.
