Temp gauge not working Chevy C15

[TCLARK]

I took the whole gauge right out and found an open between
a wire post and the inside frame, I scratched it up and used flux and a skinny
soldering gun and was able to lay some solder on the connection.
I reassembled and tested and now it deflects to full hot when I
ground the sender wire. Now to see what will happen when I get
the engine operating temp!

Thanks Phil and Frank I will see tommorrow if I can warm the engine
right up and get a reading. All 4 original gauges will be working then!
Cheers
Terry

PS Phil do you know how the wiper vacuum hose is plumbed thru the dash??
