OVERLOAD PROTECTION FOR ENGINE
D-C ELECTRICAL SYSTEM
Engine cranking, start up and running are controlled by
a solid state Engine Controller circuit board. Battery
voltage is delivered to that circuit board via 10 amp
circuit breaker and 14 amp in-line fuse. These overcurr­
ent protection devices will open if circuit is overloaded.
CAUTION! If a circuit breaker opens or a fuse ele­
ment melts, you should find the cause of the over­
load before resetting the circuit breaker or replacing
the fuse.
10 amp Circuit Breaker: If the circuit breaker opens
due to an overload, you cannot crank or start the engine.
The circuit breaker is a "push-to-reset“ type. For emer­
gency shutdown, pull the circuit breaker open. Also see
"Generator Control Panel" on Page 5.
14 Amp Fuse: If the fuse element melts open, you
cannot crank or start the engine. If you must replace
the fuse, use only identical 14 amp fuse (Figure 9).
30 amp Fuse: The generator set battery is charged
during operation by a d-c alternator, driven by the en­
gine. This 30 amp fuse protects the charging circuit
against overload. Should you need to replace the fuse,
use only an identical 30 amp fuse (Figure 10).
