Reply to "water temperature sending unit"

Hi Larry,

Actually I found your 'chevy' comment very funny, and absolutely no offense was taken.

Staying on the topic of the temperature gauge, my problem may have shifted.

I installed a new sending unit at the water pump and ran the same wire to it, but I don't appear to be getting a signal to the gauge.

Yesterday I tested the gauge by sending current through the wire conecting it to the sending unit. It worked. So I hooked it all up in the same manner as it was before and ran the motor till hot. No movement of the gauge needle. Possibly it was not hot enough, but the expansion tank was too hot to touch, so I assume that the same heat existed at the sending unit. The sending unit came with teflon tape on the threads, but I can't imagine that there is no ground because of that. Even the water would be causing a connection.

Any ideas what to try next?

Thank you,

Tom
