 FUEL GAUGE INSPECTION
 Connect the fuel unit wire connectors and
 turn the ignition switch "ON".
 Before performing the following test,
    operate the turn signals to determine that
    the battery circuit is normal.
 Check the fuel gauge needle for correct
 indication by moving the fuel unit float up
 and down.

 The fuel gauge is normal if it operates as
 above indicated. If not, check for loosely
 tightened nuts, poorly connected terminals or
 shorted wires.
