is there a fusable link

Totally agree, if the IVR is burned out all three gauges are bad, think it is just the temp for him.

I am going to change out this temp sending unit. I took the wire that plugs onto the sending unit and grounded it and the needle on the gauge in the cluster went to the hot side so maybe the sending unit is bad.

I do have electronic understanding.

I unplugged the wire from the temp sending unit on the engine and hooked a wire from it to gnd and the needle on the gauge in the cluster went all the way over to the hot side so it may be the temp sending unit after all. I am going to change it out and check it again.
