To test the feeder winding:

1.Connect the volt/ohmmeter probes to leads #31 and #32 where they connect to circuit 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 probe pins at pin A (for lead #32) and pin J (for lead #31). See Figure F.12. However, if you use this method and you 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 #32 and the other probe at amphenol pin J.

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

3.Check the AC voltage reading. It should be between 118 and 126 VAC.

4.Connect the volt/ohmmeter probes to leads #41A and #42A where they connect to circuit breaker CB8 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 probe pins at pin K (for lead #42A) and pin I (for lead #41A). See Figure F.12. However, if you use this method and you 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 #42A and the other probe at amphenol pin I.

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

6.Check the AC voltage reading. It should be between 40 and 46 VAC.
