INSPECTION
Remove the front cover.
Remove the regulator/rectifier 5P coupler
and check for continuity between the wire
harness terminals according to the
following :
Item (Wire Color) Judgement
Between battery (red) Battery has
and engine ground voltage
Between ground (green) Continuity exists
and engine ground
Between lighting wire
and engine ground
(Remove the resistor Battery has
coupler and auto voltage
bystarter coupler and
turn the lighting switch
OFF for inspection)
Between charging coil A.C. generator
(pink) and engine ground coil has
resistance
REGULATOR/RECTIFIER
INSPECTION
Pink Black Green
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
tester in an improper range may give
false readings. Red Yellow
- Kowa Electric Tester
- Sanwa Electric Tester
- Kowa Electric Tester TH-5H
· Proper range for testing: Probe
Probe(-) Black Pink Red Yellow Green
- Use XK range for Sanwa Tester Black 4 8.5 4 0.5
- Use X100 range for Kowa Tester
· If the dry battery in the tester is weak, Pink 3.5
the readings will be incorrect. In this Red
case, check the dry battery.
· The Kowa tester readings are 100 Yellow 3.5
times the actual values. Be careful Green 0.5 5K-100K 8 3.5
during testing.
Replace the regulator/rectifier if the
readings are not within the specifications in
the table.

An excellent service and not too long too wait for the part to be delivered. I live in Germany and its not easy to get spare parts here. I hope not to need your services again but if I do I will have no hesitation in doing so. John W. Parmley
