INSP CHECKING AND CHARGING THE BATTERY ELECTRICAL SYSTEM CHECKING AND CHARGING THE BATTERY WARNING Batteries generate explosive hydrogen gas and contain electrolyte which is made of poi- sonous and highly caustic sulfuric acid. Therefore, always follow these preventive measures: • Wear protective eye gear when handling or working near batteries.
Page 102 INSP CHECKING AND CHARGING THE BATTERY 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.

ELEC SWITCH CHECK SWITCH CHECK Check the continuity between the switch terminals to verify whether connections are correct. To check the switch, read the following points. SWITCH CONNECTION The table shown here contains the connections between the switch terminals (eg main switch, handlebar switches, brake switch, light switch etc).
Page 310 ELEC SWITCH CHECK 1. Detach the main switch connector from the harness connector. CAUTION When detaching the connector, do not pull by the cables. This way the cables might discon- nect from the terminals inside the connector itself. 2. Check to see if any cables are disconnected from their terminal inside the connector.
Page 311 ELEC SWITCH CHECK NOTE: Use the thin tester terminals to check continuity, as the terminals might come into contact with oth- ers inside the connector. • Check continuity between “R” and “Br” at switch positions ON (1), OFF (2) and PARK (3). There must be continuity (ie the tester must show “0”) at ON and there must be no continu- ity (ie the tester must show “∞”...

ELEC LIGHT INSPECTION LIGHT INSPECTION (HEADLIGHTS, TAIL LIGHT AND BRAKE LIGHTS, DIRECTION INDICATOR LIGHTS, INSTRUMENT LIGHTS, ETC) Check the continuity between the bulb terminals to see that they are undamaged. BULB TYPES The bulbs used are classified as shown to the left according to type of attachment.
Page 313 ELEC LIGHT INSPECTION CAUTION: When removing a bulb be careful to hold the bulbholder or its housing firmly. Never pull the cable, as it might detach from the terminal inside the connector. WARNING Keep inflammable products and hands well away from bulbs when they are on (danger of burns and fire).
