STARTER AND CHARGING SYSTEMS
47
Testing
The charging system will produce AC and DC volt-
ages. The rectifier for the DC voltage is inside of the
stator and is not serviceable. To test the charging sys
-
tem:
1. Locate the charger harness. It will be by the right
handle bar of the snow thrower when the engine
is installed.
See Figure 6.15.
2. Start the engine and run it at full throttle.
3. Connect the black (-) lead of a digital multimeter
to a good ground on the engine.
4. Set the multimeter to read AC voltage.
5. Back probe the yellow wire in the charger har-
ness with the red (+) lead of the multimeter.
See Figure 6.16.

6. The multimeter should read a voltage of 13 -
18Vac.
7. Set the multimeter read DC voltage.
8. Back probe the red wire of the charger harness.
See Figure 6.17.
9. The multimeter should read 17 - 26Vdc.
10. If the results do not match what is listed above,
check the magnets on the rotor.
NOTE: If the magnet are still magnetic, replace
the stator.
