Charging System
Stator Coil Resistance
•
Disconnect the stator coil lead connector [A].
•
Measure the stator coil resistance.
(Electric Starter Model)
○
Connect an ohmmeter between stator pins [B].
Stator Coil Resistance
0.1 ∼ 0.14 Ω
If the measured value is not within the specification, re-
place the stator coil with a new one.
If the coil has normal resistance, but the voltage inspec-
tion shows the alternator to be defective; the flywheel
magnets have probably weakened, and the flywheel must
be replaced.
•
Check for continuity between each stator pin and ground.
There should be no continuity (infinite ohm).
If the stator coil fails any of these tests, replace the coil
with a new one.
Unregulated Stator Output
•
Disconnect the stator coil lead connector [A].
•
Connect AC voltmeter to the stator pins [B].
•
Start the engine. Run the engine at the 3 000 rpm speed.
•
Voltage reading should be minimum 26 V AC/3 000 rpm.
If the AC voltage reading is less than the specification,
replace the stator with a new one.
Unregulated Stator Output (MIN)
26 V AC/3 000 rpm
