CHECKING AND CHARGING THE BATTERY
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:
•
upper rear cover
Refer to
“
PASSENGER SEAT AND SIDE
COVERS
”
.
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
4. Check:
•

a. Connect a pocket tester to the battery termi-
nals.
NOTE:
_
•
The charge state of an MF battery can be
checked by measuring its open-circuit volt-
age (i.e., the voltage when the positive termi-
nal is disconnected).
•
No charging is necessary when the open-cir-
cuit voltage equals or exceeds 12.8 V.
b. Check the charge of the battery, as shown
in the charts and the following example.
Example
c. Open-circuit voltage = 12.0 V
d. Charging time = 6.5 hours
e. Charge of the battery = 20 ~ 30%
