ALTERNATOR
The CM mower 40-amp alternator is belt-driven
from the engine crankshaft pulley. It is important
that belt slippage does not occur, or the
charging system will be affected. To adjust the
belt, see the instructions previously given under
the“Fan Belt”section.
Other than belt adjustment, the only alternator
maintenance required is to periodically inspect
the terminals to ensure they are clean and tight.
The alternator cooling fan should also be
cleaned periodically.
When working on or checking the alternator,
adhere to following precautions or alternator
damage may occur:
•
Do not UNDER ANY CIRCUMSTANCES
short the field terminal of the alternator to
ground.
•
Don not disconnect the alternator output
lead or battery cables while the alternator is
operating.
•
Do not remove the alternator from the tractor
without first disconnecting the negative (-)
bettery cable. When removing the battery,
disconnect the negative (-) cable first.
•
To install a battery, MAKE SURE that the
positive (+) cable is connected first and that
the negative terminal is connected to ground.
Reverse polarity will destroy the rectifier
diodes in the alternator.
If the battery charge warning light illuminates,
indicating that the alternator is not charging the
battery, check the fan belt and the wiring
connections. If these items are in satisfactory
condition and the warning light continues to
indicate no charge, consult your SHIBAURA
Dealer.
