BATTERY INSPECTION AND CHARGING
NOTE:
Since MF batteries are sealed, it is not possi-
ble to check the charge state of the battery by
measuring the specific gravity of the electro-
lyte. Therefore, the charge of the battery has to
be checked by measuring the voltage at the
battery terminals.
1. Remove:
• Seat
2. Disconnect:
• Battery leads
(from the battery terminals)
CAUTION:
First, disconnect the negative battery lead
1, and then the positive battery lead 2.
3. Remove:
• Battery band
