To test the 120 VAC wire feeder supply:
NOTE: The wire feeder AC voltage supply tests
require that the meter probes be inserted into the
Amphenol connection cavities. Care should be
taken to avoid damaging or expanding the termi-
nals when inserting the probes.
NOTE: The 120 VAC power supplied to the 14 pin
Amphenol connector originates from the same
winding that supplies the 120 VAC receptacles. If
the machine has previously passed 120VAC aux-
iliary winding test, this test can only reveal prob-
lems in connections or components between the
Amphenol and the stator winding.
1. Connect the voltmeter probes to pins “A”
(lead #32) and “J” (lead #31) of the 14 pin
Amphenol. See figure #3 and wiring dia-
gram.
2. Start the engine and run it at high idle (3625
to 3675 RPM).
3. The AC voltage reading should be between
120 and 135* VAC.
4. If these voltage readings are not within spec-
ifications, check for a tripped or defective cir-
cuit breaker, faulty connections, or broken
wires between the test points and the stator
windings. See wiring diagram.
