OUTPUT PROBLEMS
1. Check for faulty extension
cords, tools, lights, etc. Plug in
a known working device.
2. Check for
breakers.
3. If the Outback® has optional
GFCI receptacles, try resetting
them.
NOTE: Engine must be running at
high idle RPM or the GFCI
receptacles will not reset.
1. The output control may be set
too low.
2. Engine RPM may be low.
3. The battery may be faulty.

rectifier is probably faulty.
5. If the is voltage at the rectifier
output, but not at the weld
terminals, the choke may be
open.
1. Check for AC voltage at the

present, one or more circuit
breakers may be defective.
3. If AC voltage is not detected in
step 2 above, check leads
between the test points and the
stator winding. If the leads are
good, the stator is likely
defective.
1. Perform the Engine RPM
adjustment procedure.
2. The brushes and slip rings may
be worn or faulty. Perform the
