Not too sure what you mean by with all wires disconnected but does it do that when you have the car on ? Maybe the wire got crushed and is going to ground now.

not sure about this car, but i know that on other cars i have tested the temp gauge by grounding the sending wire- this makes the temp gauge max out (if it is working properly). so it sounds like it is grounded somehow and that may be why it is reading as it is.

thanks that totally passed my mind my problem now is figuring out what wires im looking for.i had disconnected every wire that ran to the cooling system and it still pegged hot as soon as i turned on the key.

Ok i checked the wires and cant find anywhere that its grounding out. My other problem is its running rich and ive replaced the plugs,plug wires, and the distributor cap. I am losing my mind on this car. I love this car and want to fix it. Any help would be truly appreciated.
