MAIN HARNESS CIRCUIT Regulator/Rectifier
INSPECTION
Remove the front covers. ( 2-2)
Remove the regulator/rectifier 4P coupler
and check for continuity between the wire
harness terminals according to the
following :
Item (Wire Color) Judgment
Between battery (red) Battery has
and engine ground voltage
Between ground (green) Continuity exists
and engine ground
Between lighting wire
(yellow) and engine
ground (Remove the A.C. generator
resistor coupler and auto stator has
bystarter coupler and resistance
turn the lighting switch
OFF for inspection)
Between charging coil A.C. generator
(white) and engine stator has
ground resistance
REGULATOR/RECTIFIER
INSPECTION White Red
If the main harness terminals are normal,
check the regulator/rectifier coupler for
loose connection and measure the
resistances between the regulator/rectifier
terminals.
· Do not touch the tester probes with
your finger because human body has
resistance.
· Use the following specified testers for
accurate testing. Use of an improper Green Yellow
tester in an improper range may give
false readings.
Testing instrument
YF-3501
· If the dry battery in the tester is weak, Probe
White Yellow Red Green
Probe(-)
the readings will be incorrect. In this
case, check the dry battery. White
Yellow 10.75M
Red 6.62M
Replace the regulator/rectifier if the Green 11.17M
readings are not within the specifications in
the table.
