To test the 42 VAC wire feeder winding:
1. Connect the voltmeter probes to pins “I” (lead
41A) and “K” (lead #42A) of the 14 pin Amphenol. See Figure F.12.
2. Start the engine and run it at high idle (3625 to 3675 RPM).
3. The AC voltage reading should be between
40 and 50 VAC.
4. If these voltage readings are not within the specified limits, check for a tripped or defec- tive circuit breakers, loose connections, or broken wires between the test points and the stator windings. If there are no wiring prob- lems, and the circuit breakers are not tripped or defective, the stator is defective and should be replaced.
To test the three-phase weld winding:
1. Locate weld winding leads W1, W2, and W3 where they connect to the
2. Start the engine and run it at high idle (3625 to 3675 RPM).
3. Check for about 60 to 65 VAC from leads W1 to W2, W2 to W3, and W1 to W3.
4. If these voltage readings are not within the specified limits, check for loose connections or broken wires between the test points and the stator windings. If there are no wiring problems, the stator is defective and should be replaced.
* These values ar maximum for a cold machine.
