Regulator/Rectifier
Harness side circuit inspection
Remove the regulator / rectifier coupler, and
check the wiring circuits at each terminal of the
main harness coupler.
Inspection Items
Item
Battery voltage must be
Battery (red)
between red(+) and earth(-)
Power must be connected
Ground wire (green)
between the green and the earth.
Yellow-to-yellow standard
Charging coil Resistance value. Power should
lead(yellow) not be connected between
The yellow and the earth.
The battery must carry voltage
Voltage detection when the main switch is turned
Lead(black) ON between the black (+)
and green(-)
Regulator/Rectifier Inspection
If the inspection of the harness side proves to be
satisfactory, check the regulator / rectifier coupler
for faulty connection, and measure the resistance
between the terminals of the regulator / rectifier.
NOTE
If the metal part of the tester knob makes contact
with fingers during test, body resistance will be
displayed. Take due precautions.
Use designated testers for the inspection. If
nondesignated testers are used, accurate testing
cannot be carried out because abnormal
resistance values are displayed.
Tester: PVA multi-tester
If the terminal-to-terminal resistance values
deviate from the specified values, replace the
regulator / rectifier.
