9.9 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 (2) to charge the battery.
If the engine alternator charging warning indicator
illuminates, perform the following checks:
1. Check 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. 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.
