Temp Sender

[farmallboy15]

So my root problem is that the temp gauge pegs hot and stays there. From my reading, pegging means there is a short to ground somewhere. I have a new gauge and a new connector for the sender. I don't believe there to be any breaks in the wire leading to the sender and have voltage to the sender.

With that said, I am having trouble with senders unless I am wrong.

My old sender reads .5 ish ohms cold. 150 or so hot. After testing 3 NEW senders, from 2 different stores, they all read the same cold!!??

Shouldn't they read in the 600 range cold and as they heat up resistance goes down, giving the gauge a better ground, making the needle go to the hot side!?

Thanks for the help. This truck has been nothing but problems but hopefully it is nice when it's finished... I'm getting there... Slowly...
