Temperature sending unit problem.

He says:

129 ±10% ohms at 100°F
17.7 ±6% ohms at 220°F
11.8 ±5% ohms at 250°F
Ok! Thanks. I’ve been looking at the wiring running to the temperature sending unit and noticed that some of the insulation is burned off. I think the wire is being grounded somewhere it isn’t supposed to be so I’m replacing the wire and seeing if the fixes anything.
