To check the sending unit wiring for resistance: Disconnect the wire at the sending unit and the gauge. Run a jumper wire from one end of the wire with the other end near the other end of the sending unit wire. Measure the resistance. It S\B zero ohms.
To check the sending unit for grounding: One ohm meter probe on the body of the sending unit and one probe on battery ground. Use a jumper wire from battery ground to the vicinity of the sending unit if necessary.
