Fuel Level Gauge

  1. Using Rotunda Tester (21 0015), test fuel level gauge and Instrument Voltage Regulator (IVR). Disconnect connector from fuel sender and attach to tester. Turn ignition switch to "ACC" position.
  2. Set tester switch to "IVR CHECK" position. If light flashes on and off, the IVR and wiring are functional. If "IVR CHECK" light is on steady, check IVR ground screw. If ground screw is secure, replace IVR. If "IVR CHECK" light does not come on, check for open circuit in gauge and/or circuit wiring.
  3. With tester switch in either "HIGH" or "LOW" position, center line of gauge pointer should be within "F" or "E" White band of tester. If so, fuel indicating system is working properly and replacement of fuel sender is necessary.
  4. If pointer is outside the "E" White band, replace fuel gauge. If outside "F" White band, replace IVR and retest. If still outside, replace fuel gauge and reinstall original IVR.
