The Stovebolt Site Forums The Shop Area The Electrical Bay Zeroing temp gauge to sender

I have the 1945 GMC ½ ton with the 302 gmc straight 6. My question is, I think I have the wrong sending unit in my motor. I may have mixed a chevy 235 sending unit with the one that should have been installed. To verify, what should the high and low range ohm’s be on the stock 45 GMC temp gage? Any help is appreciated.
