(2) Main Switch

(For non-accessible maintenance-free type batteries.)
Maintenance-free, non-accessible batteries are designed to
eliminate the need to add water. Yet the volume of electrolyte above
plates may eventually become depleted due to abnormal conditions
such as high heat or improper regulator setting. Use voltmeter to
check the state of charge. (See reference chart below to determine
if charging is necessary.)

 Direction for Storage
1. When storing the machine for long periods of time, remove the
battery from machine, adjust the electrolyte (3) to the proper
level and store in a dry place out of direct sunlight.
2. The battery self-discharges while it is stored. Recharge it once
every three months in hot seasons and once every six months
in cold seasons.

Main Switch
1. Open the bonnet.
2. Disconnect the 4P connector and remove the main switch (1).
3. Perform the following checks.

Connector Voltage
1. Measure the voltage with a voltmeter across the connector B
(red) terminal and chassis.
2. If the voltage differs from the battery voltage (11 to 14 V), the
wiring harness is faulty.
