Electrical System and Components

2. Keep the cables, terminals, and external surfaces

of the battery clean. A build-up of corrosive acid

or grime on the external surfaces can cause the

battery to self-discharge. Self-discharge occurs

rapidly when moisture is present.

3. Wash the cables, terminals, and external surfaces

with a mild baking soda and water solution.

Rinse thoroughly with clear water.

NOTE: Do not allow the baking soda solution to

enter the cells, as this will destroy the

electrolyte.

Battery Test

To test the battery, you will need a DC voltmeter.

Perform the following steps (see Figure 8-2):

1. Connect the voltmeter across the battery

terminals.

2. Crank the engine. If the battery drops below 9

volts while cranking, the battery is too small,

discharged, or faulty.

Battery

General

A 12-volt battery with 400 cold cranking amps is

generally recommended for starting in all conditions.

A smaller capacity battery is often sufficient if an

application is started only in warmer temperatures.

Refer to the following table for minimum cold

cranking amp (cca) capacities, based on anticipated

ambient temperatures. The actual cold cranking

requirement depends on engine size, application, and

starting temperatures. The cranking requirements

increase as temperatures decrease and battery

capacity shrinks. Refer also to the operating

instructions for the piece of equipment for specific

battery requirements.

Battery Size Recommendations

If the battery charge is not sufficient to turn over the

engine, recharge the battery.

Battery Maintenance

Regular maintenance is necessary to prolong battery

life.

WARNING: Explosive Gas!

Batteries produce explosive hydrogen gas while being

charged. To prevent a fire or explosion, charge batteries only

in well ventilated areas. Keep sources of ignition away from

the battery at all times. Keep batteries out of the reach of

children. Remove all jewelry when servicing batteries.

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.

1. Regularly check the level of electrolyte. Add

distilled water as necessary to maintain the

recommended level.

NOTE: Do not overfill the battery. Poor

performance or early failure due to loss

of electrolyte will result.
