Well I did end up getting the sending unit and temp gauge in today. Didn't know the package was here til after dark. Looks like I'll be putting it back together tomorrow after I pick up the radiator. I'll do the testing with the old hoses til the new ones arrive.
Couple questions...
1) What is the small flathead adjusting screw for, that has plastic around it on the back of the gauge?
2) There's three male terminals on the back of the gauge. The upper left terminal has "B" stamped beside it, the upper right terminal has "T" stamped beside it, and the bottom terminal has what looks to be a "number 1 with 3 lines" stamped under the 1. There's a long line, a shorter one, then the shortest one.
Anybody have any information about this? Thanks
