Temp gauge not working Chevy C15

[TCLARK]

Thanks Phil
I checked and cleaned that all good, the problem points
to the gauge, or mixed up wires to the gauge. I took pics of
the back of the dash before I took it apart and it was wired as I have
done, but it was not original wiring.

Frank, I dont know if the gauge will separate from the housing
probably should.

Cheers

yes the whole thing comes apart, I'll check and see what i have

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??

I checked stock and I do not have any temp gauges but I do have fuel and oil and speedos all NOS

Awesome Frank, that is so good to know, after I get the wipers up and running
I am tackling the speedo.
Do you happen to have a speedo cable or know where to get one.
I really need the outer part and I can probably put a new cable
inside!
