TEST PROCEDURE
To test the 115 VAC winding:
1. With the 5/16” and 3/8” nut drivers, remove
the sheet metal screws from the left case
side.
2. Carefully remove the left case side.
3. Set the voltmeter to the AC volts position.
4. Connect the voltmeter probes to leads #3
and #5 where they connect to the 115VAC
receptacle. See Figure F.3.
5. Start the engine and run it at high idle (3700
RPM).
6. Set the output control to the maximum
position (position 10).
7. Check the AC voltage reading. It should be
approximately 125VAC.
To test the 230 VAC winding:
1. With the 5/16” and 3/8” nut drivers, remove
the sheet metal screws from the left case
side.
2. Carefully remove the left case side.
3. Set the voltmeter to the AC volts position.
4. Connect the voltmeter probes to leads #6
and #3 where they connect to the 230 VAC
receptacle.
NOTE: It is easier to insert the probes directly
into the receptacle to perform this test.
However, the probes may not reach in far
enough to make or keep a good connection.
In this case, before you start the engine, insert
two test probes into the receptacle. Hold the
test probes firmly in place to measure voltage
(step 7).
5. Start the engine and run it at high idle (3700
RPM)
6. Set the output control to the maximum
position (position 10)
7. Check the AC voltage reading. It should be
approximately 240 VAC.
