Charging System Inspection
Electric Leakage Inspection
Remove earthing wire from storage battery, connect
voltmeter between storage battery negative terminal
and earthing wire. Inspect if there is short circuit
with main switch plate at position OFF.
Connect circuit tester positive terminal to
storage battery wire and negative terminal to negative
terminal of storage battery.
In case of abnormality, inspect if there is
short circuit in main switch or main wire.
Charging Inspection
Inspect by means of a circuit tester with storage battery fully charged.
Mount fully charged storage battery on preheated Engine.
Connect an ammeter between storage battery terminals.
。
Remove main fuse and connect an ammeter between
terminals.
Connect engine to tachometer.
Start engine, gradually raise its speed and
measure limiting voltage and current.
Limiting voltage/current:
14
～
15V (5000r/min)
In case limiting voltage is not in specific range,
inspect voltage adjusting rectifier.
。
Lighting System Limiting Voltage Inspection
Remove front cover.
Set circuit tester at AC position.
Limiting voltage: 13.l
±
0.5V (5000r/min)
In case limiting voltage is not in specific
range, inspect voltage adjusting rectifier.
