Low Fuel Indicator

  1. When ignition is turned on tank indicator should come on if fuel level is below 1/4 of a tank. Otherwise it should turn off. If operation is faulty, perform the following test at the low fuel wiring connector, with ignition turned on.
  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 should 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, blown fuse or defective bulb. If all terminals test properly, check gauge and IVR. If both are good, replace low fuel indicator switch/sensor.
