4. CHECKING, DISASSEMBLING AND SERVICING
[1] CHECKING AND ADJUSTING
CAUTION
• To avoid accidental short circuit, be sure to attach the positive cable to the positive terminal before the
negative cable is attached to the negative terminal.
• Never remove the battery cap while the engine is running.
• Keep electrolyte away from eyes, hands and clothes. If you are spattered with it, wash it away completely
with water immediately.
• Keep sparks and flames away from the battery at all times. Hydrogen gas mixed with oxygen becomes
very explosive.
â–
• If the machine is to be operated for a short time without battery (using a slave battery for starting), use
additional current (Lights) while engine is running and insulate terminal of battery. If this advice is
disregarded, damage to alternator and regulator may result.
(1) Battery
Battery Voltage
1. Stop the engine and turn the main switch off.
2. Connect the COM (−) lead of the voltmeter to the battery’s
negative terminal post (2) and the (+) lead to the positive terminal
post (1), and measure the battery voltage.
3. If the battery voltage is less than the factory specification, check
the battery specific gravity and recharge the battery.

Battery Terminal Connection
1. Turn the main switch on, and turn on the head light.
2. Measure the voltage with a voltmeter across the battery’s positive
terminal post and the cable terminal, and the voltage across the
battery’s negative terminal post and the chassis.
3. If the measurement exceeds the factory specification, clean the
battery terminal posts and cable clamps, and tighten them firmly.

(2) Main Switch
Connector Voltage
1. Remove the front panel.
2. Disconnect the 4P connector from the main switch.
3. Measure the voltage with a voltmeter between the connector
terminal and the chassis.
4. If the voltage differs from the battery voltage, the wiring harness
is faulty.
