To test the field winding:

1.Remove the fuel cap and lift bale 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 (3700 RPM).

4.Set the output control to the maximum position (position 10).

5.Check the AC voltage reading. It should be between 40 and 50 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 bale gasket.
