Battery Current Leakage Inspection

Inspect the battery current leakage in the following
procedures:
1) Turn the ignition switch OFF.
2) Remove the seat. Refer to "Exterior Parts Removal
and Installation in Section 9D (Page 9D-6)".
3) Disconnect the battery (–) lead wire.
4) Measure the current between (–) battery terminal
and the (–) battery lead wire using the multi-circuit
tester. If the reading exceeds the specified value,
leakage is evident.
CAUTION
!
• In case of a large current leak, turn the
tester to high range first to avoid tester
damage.
• Do not turn the ignition switch ON when
measuring current.

Section 9D (Page 9D-6)".

Repair Instructions

Regulated Voltage Inspection

B718H11A06001
Inspect the regulated voltage in the following
procedures:
1) Remove the seat. Refer to "Exterior Parts Removal
and Installation in Section 9D (Page 9D-6)".
2) Start the engine and keep it running at 5 000 r/min
with the dimmer switch turned HI position.
3) Measure the DC voltage between the (+) and (–)
battery terminals using the multi-circuit tester. If the
voltage is not within the specified value, inspect the
generator and regulator/rectifier. Refer to "Generator
Inspection (Page 1J-3)" and "Regulator / Rectifier
Inspection (Page 1J-8)".
NOTE
When making this test, be sure that the
battery is in fully charged condition.
