Lift the fuel tank and support it (page 3-4).
Disconnect the alternator 3P (Gray) connector [1] from
the regulator/rectifier.
Check the connector for loose contacts or corroded
terminals.
Measure the resistance between the Black wire
terminals of the alternator side 3P (Gray) connector.
STANDARD: 0.1 – 1.0 Ω (20°C/68°F)
Check for continuity between each wire terminal of the
alternator side 3P (Gray) connector and ground.
There should be no continuity.
Replace the alternator stator if the resistance is out of
specification, or if any wire has continuity to ground.
For alternator stator replacement (page 12-4).
