ELECTRICAL

1. Remove:

• Seat

2. Disconnect:

• Battery leads

(from the battery terminals)

First, disconnect the negative bat-
tery lead "1", and then the positive
battery lead "2".

3. Remove:

• Battery band
• Battery

4. Measure:

• Battery charge

Measurement steps:

a. Connect a pocket tester "1" to the

battery terminals.

• The charge state of an MF battery

can be checked by measuring its
open-circuit voltage (i.e., the volt-
age when the positive terminal is
disconnected).

• No charging is necessary when the

opencircuit voltage equals or ex-
ceeds 12.8 V.

b. Check the charge of the battery,

as shown in the charts and the fol-
lowing example.

Example

Open-circuit voltage = 12.0 V
Charging time = 6.5 hours
Charge of the battery = 20–30%

A. Relationship between the

open-circuit voltage and the
charging time at 20 °C (68 °F)
(These values vary with the
temperature, the condition of
the battery plates, and the
electrolyte level.)

B. Open-circuit voltage
C. Charging time (hours)
D. Time (minutes)
E. Charging condition of the bat-

tery

F. Ambient temperature 20 °C

(68 °F)

a. Charging
b. Check the open-circuit volt-

age

5. Charge:

• Battery

(refer to the appropriate charging
method illustration)

Do not quick charge a battery.

• Never remove the MF battery

sealing caps.

• Do not use a high-rate battery

charger since it forces a high-
amperage current into the bat-
tery quickly and can cause bat-
tery overheating and battery
plate damage.

• If it is impossible to regulate the

charging current on the battery
charger, be careful not to over-
charge the battery.

• When charging a battery, be sure

to remove it from the machine. (If
charging has to be done with the
battery mounted on the machine,
disconnect the negative battery
lead from the battery terminal.)

• To reduce the chance of sparks,

do not plug in the battery charger
until the battery charger leads
are connected to the battery.

• Before removing the battery

charger lead clips from the bat-
tery terminals, be sure to turn off
the battery charger.

• Make sure the battery charger

lead clips are in full contact with
the battery terminal and that they
are not shorted. A corroded bat-
tery charger lead clip may gener-
ate heat in the contact area and a
weak clip spring may cause
sparks.

• If the battery becomes hot to the

touch at any time during the
charging process, disconnect
the battery charger and let the
battery cool before reconnecting
it. Hot batteries can explode!

• As shown in the following illus-

tration, the open-circuit voltage
of an MF battery stabilizes about
30 minutes after charging has
been completed. Therefore, wait
30 minutes after charging is com-
pleted before measuring the
open-circuit voltage.
