Alternator - Inspect
This section refers to the alternator for charging
the battery. For information about the generator
alternator, refer to the OEM for the appropriate
information.
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.

the reverse direction of the normal flow.
8. Prior to installation, inspect any O-rings or seals
for damage. If necessary, replace the O-rings or
seals.
9. Inspect the core for trapped debris and
cleanliness. If it is necessary, remove the debris
and repeat the cleaning procedure.
