Update:

I have the sender in my hand. I have the gauge housing apart.

The sender with no attachments reads 25ohms at hi thru 260ohms at lo. I assume these readings are good? The sender is good?

The gauge has positive (I), Negative center bolt, and Sender (S) wire. As well as light positive wire. I placed a jumper on the gauge from neg to S with the tank sender wire removed. The guage goes from Empty to Full. This tells me the gauge is good?

Next I placed a jumper from the sender base plate to the gauge negative (with the negative wire on the gauge too) and a jumper wire from the sender center bolt to the gauge sender (with the tank sender wire removed.) The gauge alway goes to full.

When the sender is in the lo position the gauge goes to full. When the sender in the hi position, I notice the gauge goes well beyond the full mark.

Any ideas?

ps. ignore my ohms reading on my first post. my tester was not working correctly.
