4d. With the engine running at 2,000 RPM,
energize the load tester to draw amper-
age from the system.
4e. Read the amperage on the meter.
4f. If the output is less than 25 amps @2,000
RPM, test the regulator / rectifier:
See Figure 9.61.
NOTE: Output varies with load. A fixed-load
battery tester can be used to apply enough load
to test the charging system out-put.
NOTE: If there is a problem with a Caterpillar
alternator, refer it to a Caterpillar dealer.
5. If the output is low, but the charging system com-
ponents test good, check the rest of the system:
battery, voltage drop on the hot side, voltage
drop on the ground side, any relays that may dis-
able the charging system.

Batteries
1. Precautions: See Figure 9.62.
CAUTION: Batteries produce flammable and
explosive gas, particularly during charging:
• Do not smoke or allow an open flame or heat
source near the battery.
• Charge batteries in an open area
• Wear eye protection and gloves when handling
batteries.
• Do not allow direct metal contact across the
posts. This will produce extreme heat that may
cause direct burns or ignite flammable gas.
CAUTION: California Proposition 65 warning:
Battery posts, terminals, and related accessories
contain lead and lead compounds. These chem-
icals are known in the State of California to
cause cancer and reproductive harm. Wash
hands after handling.
NOTE: The batteries used in Current Cub Cadet
equipment are sealed. It is not possible to
check, test or add fluid.
CAUTION: Batteries contain electrolyte, which is
highly corrosive. If a battery is ruptured, neutral-
ize the electrolyte with baking soda, then care-
fully rinse the effected area with water.
2. Importance of battery charge level and condi-
tion: A fully charged battery that is in good condi-
tion is an important factor when trying to
diagnose other parts of an electrical system:
