CHECKING AND CHARGING THE BATTERY
3-48
INSP
ADJ
NOTE:
Since MF batteries are sealed, it is not possible to
check the charge state of the battery by measuring
the specific gravity of the electrolyte. Therefore, the
charge of the battery has to be checked by meas-
uring the voltage at the battery terminals.
1. Remove:
Seat
Panel 1
2. Disconnect:
Battery leads
(from the battery terminals)
First, disconnect the negative lead 1, then the
positive lead 2.
3. Remove:
Battery
4. Check:
Battery charge
CAUTION:
a. Connect a pocket tester to the battery termi-
nals.
NOTE:
The charge state of a MF battery can be
checked by measuring its open-circuit voltage
(i.e., the voltage when the positive terminal 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 %
5. Charge:
Battery
