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

I would say the room temperature was around 65 degrees.I dont think 10 degrees one way or the other should have a big effect on the guage reading. With 700 ohms ,there is a little room for error.The measurements were done on an older digital reasonable quality meter.I would bet that a sender from a much newer GM vehicle might work. GM is noted for parts interchange.
