CHARGING SYSTEM - On-Vehicle Inspection
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm,
check the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage:
12 V type 14.0-15.0 V at 25°C (77°F)
13.5-14.3 V at 135°C (275° F)
24 V type 27.7-28.7 V at 25°C (77°F)
26.0-28.7 V at 135°C (275°F)
If the voltmeter reading is more than standard voltage,
replace the IC regulator.
If the voltmeter reading is less than standard voltage, check
the IC regulator and alternator as follows:
• With terminal F grounded, start the engine and
check the voltmeter reading of terminalB.
• If the voltmeter reading is greater than standard ,
voltage, replace the IC regulator.
• If the voltmeter reading is less than standard volt-
age, check the alternator.
7. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the
high beam headlights and place the heater blower
switch at "HI".
(b) Check the reading on the ammeter.
Standard amperage:
12 V 45, 55, 60, 80 A type 30 A or more
12 V 100 A type 40 A or more
24 V 30 A type 15 A or more
24 V 55 A type 30 A or more
If the ammeter reading is less than standard amperage,
repair the alternator. (See page CH-8)
HINT: With the battery fully charged, the indication will
sometimes be less than standard amperage.
