CHARGING SYSTEM 6H-11
Higher Voltage
If voltage is higher than standard value, check ground of brushes.
If brushes are not grounded, replace IC regulator.
Lower Voltage
[60 A type]
If voltage is below or in standard value, increase engine speed up
to 2000 – 2500 rpm soon after starting engine, and read maxi-
mum value on ammeter immediately.
If current is less than 42 A, repair or replace generator.
[70 A and 80 A types]
If voltage is lower than standard value, proceed to following
check.
2) Ground F terminal and start engine, then measure voltage at
B terminal as shown in left figure.
• Voltage is higher than standard value
It is considered that generator itself is good but IC regulator
has been damaged, replace IC regulator.
• Voltage is lower than standard value
Generator itself has problem, check the generator.
LOAD CHECK [70 A and 80 A types only]
1) Run engine at 2,000 rpm and turn on head light and heater
motor.
2) Measure current and if it is less than 20 A (70A type) or 30 A
(80 A type) repair or replace generator.
