9.10 CHARGING CIRCUIT
Before using a battery charger, an attempt can be made
to recharge the battery by jump-starting the machine.
(Refer to the appropriate Operation & Safety Manual.)
Allow the engine to run, which will enable the alternator to
charge the battery.
If the engine alternator charging warning indicator
illuminates, perform the following checks:
1. Check the all battery cable connections at the
battery, and verify that they are clean and tight.
2. Check the external alternator wiring and
connections, and verify that they are in good
condition.
3. Check the fan belt condition and tension.
4. Verify that the alternator mounting hardware is tight.
5. Run the engine and check the alternator for noise. A
loose drive pulley, loose mounting hardware, worn or
dirty internal alternator bearings, a defective stator
or defective diodes can cause noise. Replace a worn
or defective alternator.
