F1 and F2 protect the stator exciter
winding from overload. If F1 opens,
weld and generator power is low or
stops entirely. If F2 opens, weld out-
put stops. 4 kVA/kW generator pow-
er is still available.

CB4 protects the welding arc drive
(dig) circuit. If CB4 opens, the elec-
trode may stick to the workpiece
more frequently during low voltage
(short arc length) conditions. CB4 au-
tomatically resets when the fault is
corrected.

CB5 protects the 24 volt AC output to
remote receptacle RC14, and 24 volt
output to field current regulator board
PC1. If CB5 opens, weld output and
24 volt output to RC14 stops.
CB10 protects the engine battery cir-
cuit. If CB10 opens, the engine will
not crank. CB10 automatically resets
when the fault is corrected.
CB11 protects the control box wiring
harness. If CB11 opens, weld output
stops (generator power is still avail-
able).
CB12 protects the field flashing cir-
cuit. If CB12 opens, the generator
may not excite at start-up and weld
and generator power output may not
be available.
CB13 protects the 115 volt AC output
to remote receptacle RC14. If CB13
opens, 115
stops.
