Remove the seat (page 3-3).
Disconnect the negative (-) cable from the battery. Connect the ammeter (+) probe to the negative (-) cable and ammeter (-) probe to the battery (-) terminal.
Check for current leakage.
NOTE:
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 the fuse in the tester.
SPECIFIED CURRENT LEAKAGE: 0.1 mA max.
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.

Be sure the battery is in good condition before performing this test.
Warm up the engine to normal operating temperature.
Connect the multimeter between the battery positive (+) and negative (-) terminals.
NOTE:
To prevent a short, make absolutely certain which are the positive (+) and negative (-) terminals or cables.
Measure the voltage on the multimeter when the engine runs at 5,000 rpm.
Standard:
Measured BV < Measured CV < 15.5 V
• BV = Battery Voltage
• CV = Charging Voltage

Remove the left side cover (page 3-3).
Disconnect the regulator/rectifier 4P (Natural) connector.
If the charging voltage reading (page 17-7) is out of the specification, check the following at the wire harness side connector:
|
Item |
Terminal |
Specification |
|
Battery charging line |
Red/white (+) and ground (-) |
Battery voltage should register |
|
Charging coil line |
Yellow and ground |
Continuity should exist |
|
White and ground |
Continuity should exist |
|
|
Ground line |
Green and ground |
Continuity should exist |
If all lines are normal and there are no loose connections at the regulator/rectifier connector, replace the regulator/rectifier unit.

Remove the left side cover (page 3-3).
Remove the wire band.
Disconnect the regulator/rectifier 4P (Natural) connector.
Remove the nut and regulator/rectifier.
Align the regulator/ Installation is in the reverse order of removal.
rectifier locating pin with the hole on the bracket.

Remove the left radiator shroud (page 3-4).
Disconnect the alternator 4P (Black) connector. Check for continuity between the terminal of the alternator side connector and ground.
CONNECTION: Yellow terminal - Body ground White terminal - Body ground
If any wire has no continuity to ground, replace the alternator stator.
For stator removal (page 12-5).
