 FUEL PUMP

 INSPECTIION                                      Full Position

 Put the side stand up and the engine stop
 switch is at "RUN"

 Disconnect the fuel pump/fuel unit
 connector.
 Connect the multimeter (+) probe to the
 Red/Black terminal and the multi-meter (-)
 probe to the Green terminal.
 Turn the ignition switch to "ON" and                                     Green
 measure the voltage between the terminals.
 It should be shown the current battery
 voltage for a few seconds.
                                                                               Yellow/White
