Charging system inspection
Alternator charging coil
Disconnect the regulator rectifier 6P (Black) connector.
Measure the resistance between the Yellow terminals of
the wire harness side.
Standard: 0.7 – 1.0  (20 ˚ C/68 ˚ F)
If the resistance is out of specification, disconnect the
alternator 3P (Natural) connector and measure the
resistance between the yellow terminals of the alternator
side connector.
If the measured resistance at regulator/rectifier 6P (Black)
connector is incorrect and the alternator 3P (Natural)
connector is correct, check the wire harness.
If the resistance is still out of specification, replace the
stator assembly.
Regulated Voltage Inspection
Disconnect the power 4P (Natural) connector.
Connect the digital voltmeter to the Red (+) and Green
(–) terminals.
Start the engine, check for regulated voltage.
