BATTERY CHARGING SYSTEM

Electrical Shock can cause injury.

Do not touch wires while engine is running.

NOTE: Observe following guidelines to avoid damage to

electrical system and components:

● Make sure battery polarity is correct. A negative (–)

ground system is used.

Connector Block

Stator

Stator is mounted on crankcase behind ﬂ ywheel. Follow

procedures in Disassembly/Inspection and Service and

Reassembly if stator replacement is necessary.

Rectiﬁ er-Regulator

Rectiﬁ er-regulator is mounted on air cleaner bracket. To

replace, disconnect plug(s), remove mounting screws,

and ground wire.

Battery

A 12-volt battery with 400 cold cranking amps (cca) is

generally recommended for starting in all conditions. A

smaller capacity battery is often suﬃ cient if an

application is started only in warmer temperatures. Refer

to following table for minimum capacities based on

anticipated ambient temperatures. Actual cold cranking

requirement depends on engine size, application, and

starting temperatures. Cranking requirements increase

as temperatures decrease and battery capacity shrinks.

Refer to equipment's operating instructions for speciﬁ c

battery requirements.

Also, disconnect all other electrical accessories in

common ground with engine.

● Prevent stator (AC) leads from touching or shorting

while engine is running. This could damage stator.

These engines are equipped with a 25 amp regulated

charging system.
