Factory temperature gauge issue
I'm having an issue with the temperature gauge on my '72. The gauge has always read cold and wouldn't move. The guy I bought the truck from said he thought that meant the gauge and not the sender was bad and provided a factory gauge replacement when I bought the truck. I finally switched out the old temp gauge and when I went to test it as soon as I hit the key the new gauge swung to the hot side and when I started the truck the gauge gauge pegged to the hot end. I have put a meter on the wire after taken off the sender and it has some resistance and is not shorted to ground. Is my new temp gauge bad, the sender bad, both or something else?
Thanks in advance for any assistance!
