Low Fuel Indicator

  1. When ignition is turned "ON", indicator should light for less than one minute. If fuel level is below 1/4 tank indicator will stay on, otherwise it should turn off. If operation is faulty, perform the following tests at the low fuel connector.
  2. Terminal 1 is blank. Connect a test lamp to terminal 2 and ground, then terminal 3 and ground. Lamp will blink on in both cases but be brighter at terminal 3. Connect test lamp between 12 volt source and terminal 4. Test lamp should be on. Connect test lamp between terminal 5 and ground - lamp will be on. Connect jumper between 12 volt source and terminal 6. Fuel indicator should light.
  3. If any test fails, check for bad wiring. If all terminals test properly, check gauge and IVR. If gauge and IVR are good, replace low fuel indicator switch/sensor.
