I am troubleshooting the fuel gauge in a '66 Chevy C10 and I have replaced the sending unit, fuel gauge and wire from sending unit to fuse block, to no avail. The under dash harness has been replaced, as well. The needle remains pegged to the past full position with the electrical connector plugged into the back of the back of the gauge, with power, without power or unplugged. Any pointers for correction of this situation?
Thanks.
Tony
