• Do not disconnect the alternator output lead or bat-
tery cables while the alternator is operating.
• Do not remove the alternator from the power unit
without first disconnecting the negative (-) battery
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 Hustler Dealer.

wire it will melt down so that it will no longer allow current to
pass (similar to the way a fuse works). The fusible link wire is
