FIGURE F.4 - LOCATION OF LEADS #7 AND #9 AT FIELD BRIDGE RECTIFIER
To test the field winding:
1. Remove the fuel cap and lift bail rubber
gasket. With the 5/16” nut driver, remove
the case top and left side; then reinstall
the fuel cap.
2. Connect the volt/ohmmeter probes to leads
#7 and #9 where they connect to the Field
Bridge Rectifier. See Figure F.4.
3. Start the engine and run it at high idle (3650
RPM).
4. Set the output control to the maximum
position (position 10).
5. Check the AC voltage reading. It should be
between 36 and 43 VAC.
If any one or more of the readings are missing
or not within specifications, then check for
loose or broken wires between the test points
and the stator windings. See the Wiring
Diagram. Make sure the windings are NOT
grounded internally to the stator iron. If the
leads are intact, then the stator may be faulty.
Replace the stator.
If the voltage readings are within specifica-
tions, then the windings are good and func-
tioning properly.
6. Reinstall the case side, case top, fuel cap,
and lift bail gasket.
