FIGURE F.4 – CONTROL PC BOARD
AUXILIARY AND FIELD WINDING TEST (continued)
FIELD WINDING
1. Remove the fuel cap and lift bail rubber gasket.
With a 5/16” nut driver or socket, 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 Control P.C. Board.
3. Start the engine and run it at high idle (3700 RPM).
4. Set the output control to the maximum position
(position 10).
5. Check the AC voltage reading. It should be
between 41 and 45 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 specifications, then
the windings are good and functioning properly.
6. Reinstall the case side, case top, fuel cap, and lift
bail gasket
