NOTE:
Since MF batteries are sealed, it is not possible
to check the charge state of the battery by mea-
suring the specific gravity of the electrolyte.
Therefore, the charge of the battery has to be
checked by measuring the voltage at the battery
terminals.
1. Remove:
S rider seat
Refer to "SEATS".
2. Disconnect:
S battery leads
(from the battery terminals)
CAUTION:
First, disconnect the negative battery lead
1 , and then the positive battery lead 2 .
3. Remove:
S battery
4. Check:
S battery charge
a. Connect a pocket tester to the battery termi-
nals.
Positive tester probe !
Negative tester probe !
NOTE:
S The charge state of an MF battery can be
checked by measuring its open-circuit voltage
(i.e., the voltage when the positive battery ter-
minal is disconnected).
S 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 X 30%
