I will give this a try and see what I come up with. Much appreciated.
The fuel gauge is not working yet because I have to put the ground strap on the new fuel tank/sending unit. The one that I got when I put the new tank in was a little too short to reach for ground, so we are going to manufacture the ground for the fuel sending unit. Not sure if it matters, but the speedometer works, charge indicator works, and oil pressure light works.
Try grounding the temp sender wire, turn the key to "run" and watch the gauge. It should "shoot" towards "hot." Don't leave the key on any longer than to see if it works
