Found 1 bad GP(#1). How will that affect the system? Also the #5 GP was not connected? but was good.
Now that I have them out should I cange all of them? And on the wires near the ring terminal there is exposed wire, just where the insulation has broken. Can that just be taped up with electrical tape?
All wires ohm out good.

Where does this system get it temp reading from? The resistance of the GP?

Thanks
Doug
