Electrical System and Components
Battery Test
Test the baery voltage by connecting a DC voltmeter
across the baery terminals and cranking the engine.
If the baery drops below 9 volts while cranking, the
baery is discharged or faulty. Refer to Figure 7-6.

A 12 volt baery with a minimum current rating
of 250 cold cranking amps is recommended. The
actual cold cranking amp requirement depends on
engine size, application and starting temperatures.
As temperatures decrease, cranking requirements
increase but baery capacity shrinks. Refer to the
operating instructions of the equipment this engine
powers for specific baery requirements.
If the baery charge is not sufficient to crank the
engine, recharge the baery. Do not jump start using
another baery.
Battery Charging
WARNING: Explosive Gases!
Baeries produce explosive hydrogen gas while being
charged. To prevent a fire or explosion, charge baeries only
in well ventilated areas. Keep sparks, open flames, and other
sources of ignition away from the baery at all times. Keep
baeries out of the reach of children. Remove all jewelry
when servicing baeries.
Before disconnecting the negative (-) ground cable, make
sure all switches are OFF. If ON, a spark will occur at the
ground cable terminal, which could cause an explosion if
hydrogen gas or gasoline vapors are present.
Battery Maintenance
Regular maintenance will ensure the baery will
accept and hold a charge.
1. Regularly check the level of electrolyte. Add
distilled water as necessary to maintain the
recommended level.
NOTE: Do not overfill the baery. Poor
performance or early failure due to loss
of electrolyte will result.
2. Keep the cables, terminals, and external surfaces
of the baery clean. A build-up of corrosive
acid or grime on the external surfaces can self-
discharge the baery. Self-discharging happens
rapidly when moisture is present.
3. Wash the cables, terminals, and external surfaces
with a baking soda and water solution. Rinse
thoroughly with clear water.
NOTE: Do not allow the baking soda solution to
enter the cells of the baery, as this will
destroy the electrolyte.

Electrical Systems Wiring Diagrams and
Battery Charging Systems
Most engines are equipped with either a 9 or 15 amp,
regulated baery charging system. Some have a 3
amp, regulated system with a 70 wa lighting circuit.
Refer to the following wiring diagrams and
troubleshooting guides to test and service the system.
NOTE: Observe the following guidelines to
prevent damage to the electrical system and
components.
1. Make sure the baery polarity is correct. A
negative (-) ground system is used.
2. Disconnect the baery cables (negative (-) cable
first), before doing electric welding on the
equipment powered by the engine.
3. Prevent the stator leads from touching or
shorting while the engine is running. This could
damage the stator.
