Fuel Gauge

  1. Connect ohmmeter between terminal "G" and 31 on fuel gauge sender. See Fig 1 . Resistance should be 2 ohms with float at full position and 70 ohms with float at empty postion. The higher the fuel level, the lower resistance will be.
  2. Connect ohmmeter across terminal "W" and 31. Continuity should exist only if tank is empty (low fuel warning contacts). If sending unit is functional and wire harness is good, replace fuel gauge.
