Starting and charging - Charging system
7. Check charging system circuit at no load.
(a) If there is battery/alternator tester, please connect tester
to charging system circuit as manufacturer instruction.
(b) If there is no battery/alternator tester, please connect volt-
meter to charging system circuit as the following way.
z Uncouple wire on engine terminal B, and connect wire
on negative (-) test bar of ampere meter.
z Connect positive (+) test bar of ampere meter to alter-
nator terminal B.
z Connect positive (+) test bar of voltmeter to alternator
terminal B.
z Connect negative test bar of voltmeter to earth.
8. Check charging system circuit at load.
(a) Turn on high beam of front combination lamps with engine running at 2000rpm,and turn blower to
“HI” position.
(b) Check the reading of ampere meter.
Standard amperage: 30A or more.
Hints:
If amperage is less than standard value, please repair alternator.
If battery is under the state of full charge, amperage may be less than standard value sometimes.
(c) Check charge system circuit.
(1) Check the readings of ampere meter and voltmeter with engine from idle speed to 2000rpm.
Standard current: 10A or less.
Standard voltage: 12.9~14.9V.
Hints:
If voltmeter reading is more than standard value, please replace with new voltage regulator.
If voltmeter reading is less than standard value, please check voltage regulator and alternator
as the following way.
(2) Earth terminal F, start engine and check voltage of
terminal B.
Hints:
If voltmeter reading is more than standard value,
please replace with new voltage regulator.
If voltmeter reading is less than standard value,
please check alternator.
