NOTE: Observe following guidelines to avoid damage to
electrical system and components:
● Make sure battery polarity is correct. A negative (-)
ground system is used.
● Make sure all ground connections are secure and in
good condition.
● Disconnect both battery cables before doing electrical
welding on equipment powered by engine. Also,
disconnect other electrical accessories in common
ground with engine.
● Prevent stator (AC) leads from touching or shorting
while engine is running. This could damage stator.
Most engines are equipped with a 3,4,10, or 18 amp
regulated battery charging system.

Stator
Stator is mounted on crankcase behind fl ywheel.
Should stator have to be replaced, follow procedures in
Disassembly.

NOTE: When installing rectifi er-regulator, push wiring
harness plug into regulator receptacle until it
locks into place.
Rectifi er-regulator is connected to engine with a
matching wiring harness containing a plug-in connector.
Grounded through wiring harness, rectifi er-regulator
is secured to equipment in a suitable location with two
mounting screws. To replace it, disconnect plug, and
remove two mounting screws.
Rectifi er-regulator converts AC voltage coming from
stator to DC voltage, while also monitoring and
controlling battery voltage. There are two diff erent
rectifi er-regulators which are used; an 18 amp and a
10 amp assembly. Although externally similar, internal
circuits diff er and two should not be interchanged.
