The Stovebolt Site Forums The Shop Area The Electrical Bay Water temp./oil press. vs. resistance curves?

Update...the attempt to use a more modern variable resistance type sender ended in failure. I did find a book at NAPA that helped somewhat. The problem is that the sender I need is a negative coefficient type (as heat rises, the resistance goes down). The King-Seeley gauge provides to much current to the sender. It starts to heat up on it's own and goes into thermal overload. So I bite the bullet, get into "[censored]-national" and buy an original King-Seeley" type sender. Thanks for the help guys.
