If the readings measured are not normal,
check parts in the circuit.
If the parts are normal, then trouble is in the
wiring.
If there is nothing wrong with parts and wiring,
replace the regulator rectifier.

Replace the regulator rectifier if the resistance
value is abnormal.
Caution
z Human body has resistor. Do not touch
the multi meter probe metal or the
measured value would be affected.
AC Generator coil inspection
Caution
z The inspection of AC Generator charge
coil / lamp coil can be proceeded on the
engine.
Measure the resistor value between AC.
Generator wiring.
Disconnect AC Generator 6 pin coupler.
The following wire should be closed circuit.
Standard value：
Yellow - pink 0.9Ω±10%
Black / red - ground 420Ω±10%
Green / white – blue / white 105Ω±10%
Light green / red (neutral switch)
Replace the AC. Generator coil if the
measured value is over the standard value.
