Stator Coil Resistance
•
Disconnect the connector [A].
•
Measure the stator coil resistance.
(Electric Starter Model)

Connect an ohmmeter between stator pins [B].
Stator Coil Resistance (Electric Starter Model)
0.01 to 0.1

(Recoil Starter Model with Electric Clutch)

Connect an ohmmeter between stator pin and engine-body.
Stator Coil Resistance (Recoil Starter Model with Electric Clutch)
4.4 to 15

If the meter does not read as specified, replace the stator coil.
If the coil has normal resistance, but the voltage inspection showed
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 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 VAC/3 000 rpm.
If the AC voltage reading is less than the specification, replace the
stator.
Unregulated Stator Output (MIN)
26 VAC/3 000 rpm
Regulator Removal
•
Remove:
Stator Coil Lead Connector [A]
Regulator Screws [B]
Regulator [C]
Regulator Installation
•
Install the regulator and tighten the screws.
