MAIN HARNESS CIRCUIT INSPECTION
Remove the front covers. (

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)
and engine ground
Battery has
voltage
Between ground (green)
and engine ground
Continuity exists
Between lighting wire
(yellow) and engine
ground (Remove the
resistor coupler and auto
bystarter coupler and
turn the lighting switch
OFF for inspection)
A.C. generator
stator has
resistance
Between charging coil
(white) and engine
ground
A.C. generator
stator has
resistance
REGULATOR/RECTIFIER INSPECTION
If the main harness terminals are normal,
check the regulator/rectifier coupler for loose
connection and measure the resistances
between the regulator/rectifier terminals.
Replace the regulator/rectifier if the readings
are not within the specifications in the table.

•
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
tester in an improper range may give
false readings.
−
Kowa Electric Tester
−
Sanwa Electric Tester
−
Kowa Electric Tester TH-5H
•
Proper range for testing:
−
Use XK
Ω
range for Sanwa Tester
−
Use X100
Ω
range for Kowa Tester
•
If the dry battery in the tester is weak,
the readings will be incorrect. In this
case, check the dry battery.
•
The Kowa tester readings are 100
times the actual values. Be careful
during testing.
