side of one of the batteries. and
connect the black lead wire (B) to the
negative side of the other battery.
Connect the red lead wire (C) (for test)
of the regulator to the regulator case.
and connect the black lead wire (D) to
the lead wire of the regulator.
3. Inspection
Checking the battery
voltage
First. set the switches, both right and
left. to "12V" "VOLT". If the checker
needle points to 20 volts or more, the
battery
voltage
is sufficient.
Thyristor working
voltage:
13.8±0.5 volts at 5.000 r/min
If the regulator is faulty:
The checker needle swings
over
the
black zone. and it will not return to 0
from 20V or more.

lamp lights up. there is continuity in the
regulator checker.
b. Operation test
Slowly slide the switch to the right. If
the needle quickly swings back to O. the
moment that it
moves
into the black
zone of the scale. the working
voltage
of
the thyristor in the regulator is in good
condition, and the regulator is also in
good condition.
