 CHARGING SYSTEM
 CURRENT LEAKAGE TEST
 Remove the seat (see page 2-3).
 Turn the ignition switch "OFF", and
 disconnect the negative (-) cable from the
 battery.
 Connect the ammeter (+) probe to the
 negative (-) cable and the ammeter (-) probe
 to the battery (-) terminal.
 With the ignition switch "OFF", check for
 current leakage.
  When measuring current using a tester,
    set it to a high range, and then bring
    the range down to an appropriate level.
    Current flow higher than the range
    selected may blow out the fuse in the
    tester.
    While measuring current, do not turn
    the ignition switch "ON". A sudden
    surge of current may blow out the fuse
    in the tester.
 Specified current leakage:
                            1 mA maximum
 If current leakage exceeds the specified
 value, a shorted circuit is likely.
 Locate the short by disconnecting
 connections one by one and measuring the
 current.

 CHARGING VOLTAGE INSPECTION
 Start the engine and warm it up to operating
 temperature; stop the engine.
 Connect the multi-meter between the
 positive and negative terminals of the
 battery.
  Make sure the battery is in good
    condition before performing this test.
    To prevent a short, make absolutely
    certain which are the positive and
    negative terminals or cable.

 With the headlight on high beam, restart the
 engine. Measure the voltage on the
 multimeter when the engine runs at 5000
 rpm.
 Limit Voltage/Current: 13.515.5V/0.5A
                          max.
