fuel gauge problems

Ohm meter doesn't say "pretty much dround out" , not one that I've seen anyway.
Ohm reading at the sender should be somewhere between 10 ohms and 73 ohms per how much fuel is in the tank. Sender wire should show the same behind the cluster also. If not that current path is flawed.

""I do have a electronic resistor that is installed and is suppose to shut down if too much power is going to the cluster."" I'm totally buffaloed by that statement. You may have created your problem there.

Temp sender wire is purple.

Good luck with it

Thats a good idea measuring the ohms at the guage end to compare it with the ohms at the sender.What i meant by"Then I ohm the sending unit and it is pretty much ground out as it sits. "I ohmed the sender off the tank strap bolt and then checked the ohms from that bolt to the other strap bolt and the readings were close to the same.I was useing a needle type reader set on x10 and it read about 6 on the sender and 5 on bolt to bolt.Also the tank is empty.
"I do have a electronic resistor that is installed and is suppose to shut down if too much power is going to the cluster."It was late when I posted this and I couldn't remember what they were called but its a solid state resistorwith a built in fail safe like the ones you offer.Actaully I seen yours after I bought mine.
Thanks for the temp wire color also.
