Temperature gauge does not work on my 1970 340 Duster ?

I have had trouble with aftermarket sensors a lot. I have a trans am that I wound up buying the sensors from a GM dealer because I couldn’t get multiple sensors to work right. The way the cooling fans work is pretty marginal, so the sensors have to be pretty accurate. Works fine with the OEM sensors.

My temp gauge isn’t working & I built a simulator box and found my wiring and gauge were ok. My temp sender reads about 6500 ohms. I could have swore I checked it before I installed it. I have a post on it in the electrical section.

I’ll send it to you if you want, just pm me your address. It fits in a small flat rate box.
