To test the feeder 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 #31 and #32 where they connect to the cir- cuit breaker CB1 and the 14 pin amphenol. See the Wiring Diagram.

NOTE: It is possible to check this voltage reading at the amphenol by inserting the test probes at pin A (for lead #32) and J (for lead #31A). See Figure 4A. However, if you use this method and get no voltage reading, it could mean there is a break or loose connection in the leads between the circuit breaker and the amphenol. Check the reading again with one probe at the circuit breaker connection for lead #31 and the other probe at amphenol pin A.

3.Start the engine and run it at high idle (3700 RPM).

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

5.Check the AC voltage reading. It should be between 115 and 126 VAC.

6.Connect the volt/ohmmeter probes to leads #31 and #42 where they connect to the cir- buit breaker CB1 and the 14 pin amphenol. See the Wiring Diagram.

NOTE: It is possible to check this voltage reading at the amphenol by inserting the test probes at pin K (for lead #42) and I (for lead #31B). See Figure 4A. However, if you use this method and get no voltage reading, it could mean there is a break or loose connection in the leads between the circuit breaker and the amphenol. Check the reading again with one probe at the circuit breaker connection for lead #31 and the other probe at amphenol pin K.

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

8.Check the AC voltage reading. It should be between 43 and 50 VAC.
