Stop engine.

When a circuit breaker, supple-
mentary protector, or fuse

opens, it usually indicates a

more serious problem exists.

Contact Factory Authorized

Service Agent.

1

Fuse F1

F1  protects the stator exciter wind-

ing from overload. If F1 opens, weld

and generator power is low or stops

entirely.

Circuit Breaker CB1 (Not

Shown)

Supplementary Protector CB8

6

Circuit Breaker CB9

CB1 protects the engine battery cir-

cuit. If CB1 opens, the engine will not

crank. CB1 automatically resets

when the fault is corrected.
CB2 protects the engine wiring har-

ness. If CB2 opens, the engine will

not crank.
CB3 protects  part of the weld control

wiring  harness. If CB3 opens, weld

and generator power output stops.
CB8 protects the 24 volt AC output to

remote receptacle RC14.  If CB8

opens, 24  volt output to RC14 stops.
Press button to reset supplementary

protector.
CB9 protects the throttle solenoid

against overload. If CB9 opens, the

engine does not automatically idle

down. Check the linkage and sole-

noid. CB9 automatically resets.
