Fuel Gauge: G20

  1. To check power source, turn ignition on. Check voltage between terminal No. 25 and ground. See Fig 1 . If battery voltage is present, go to step 3).
  2. If battery voltage is not present, check for blown fuse or fusible link. Check continuity between battery terminal and instrument cluster. Check battery circuit from ignition switch and relay. See appropriate chassis wiring diagram in the WIRING DIAGRAMS  Section.
  3. Turn ignition switch on. Connect a test light with 3.4 watt bulb between fuel gauge terminal "B(1)" and ground. See Fig 2 . If gauge needle does not move smoothly to FULL, replace gauge. If needle moves smoothly to FULL, check continuity between instrument cluster terminal No. 6 and ground. See Fig 3 .
