Alternator - Inspect

Perkins recommends a scheduled inspection of the
alternator. Inspect the alternator for loose
connections and correct battery charging. Check the
ammeter (if equipped) during engine operation in
order to ensure correct battery performance and/or
correct performance of the electrical system. Make
repairs, as required.
Check the alternator and the battery charger for
correct operation. If the batteries are correctly
charged, the ammeter reading should be very near
zero. All batteries should be kept charged. The
batteries should be kept warm because temperature
affects the cranking power. If the battery is too cold,
the battery will not crank the engine. When the engine
is not run for long periods of time or if the engine is
run for short periods, the batteries may not fully
charge. A battery with a low charge will freeze more
easily than a battery with a full charge.

Battery - Replace

Batteries give off combustible gases which can
explode. A spark can cause the combustible
gases to ignite. This can result in severe personal
injury or death.
Ensure proper ventilation for batteries that are in
an enclosure. Follow the proper procedures in or-
der to help prevent electrical arcs and/or sparks
near batteries. Do not smoke when batteries are
serviced.
The battery cables or the batteries should not be
removed with the battery cover in place. The bat-
tery cover should be removed before any servic-
ing is attempted.
Removing the battery cables or the batteries with
the cover in place may cause a battery explosion
resulting in personal injury.
1. Switch the engine to the OFF position. Remove all
electrical loads.
2. Turn off any battery chargers. Disconnect any
battery chargers.
3. The NEGATIVE "-" cable connects the NEGATIVE
i02322311
"-" battery terminal to the NEGATIVE "-" terminal
on the starting motor. Disconnect the cable from
the NEGATIVE "-" battery terminal.
4. The POSITIVE "+" cable connects the POSITIVE
"+" battery terminal to the POSITIVE "+" terminal
on the starting motor. Disconnect the cable from
the POSITIVE "+" battery terminal.
Note: Always recycle a battery. Never discard a
battery. Dispose of used batteries to an appropriate
recycling facility.
5. Remove the used battery.
6. Install the new battery.
Note: Before the cables are connected, ensure that
the engine start switch is OFF.
7. Connect the cable from the starting motor to the
POSITIVE "+" battery terminal.
8. Connect the NEGATIVE "-" cable to the
i02322315
NEGATIVE "-" battery terminal.
Battery Electrolyte Level -
Check
When the engine is not run for long periods of time or
when the engine is run for short periods, the batteries
may not fully recharge. Ensure a full charge in order
to help prevent the battery from freezing. If batteries
are correctly charged, the ammeter reading should be
very near zero, when the engine is in operation.
All lead-acid batteries contain sulfuric acid which
can burn the skin and clothing. Always wear a
face shield and protective clothing when working
on or near batteries.
1. Remove the filler caps. Maintain the electrolyte
level to the "FULL" mark on the battery.
If the addition of water is necessary, use distilled
water. If distilled water is not available use clean
water that is low in minerals. Do not use artificially
softened water.
2. Check the condition of the electrolyte with a
suitable battery tester.
3. Install the caps.
