1. Multimeter
2. Magneto harness adapter
3. YELLOW and BLACK/YELLOW wires
Insulation
– Disconnect the magneto wiring harness con-
nector.
– Install the 4-pin magneto harness adapter
(P/N 295 000 131) to the magneto wiring har-
ness. Leave wiring harness side disconnected.
– Insert multimeter positive (+) probe to the
YELLOW wire of the 4-pin magneto harness
adapter.
– Ground the multimeter negative (-) probe to the
engine or the stator iron core and note the read-
ing.

TYPICAL
1. Multimeter
2. Magneto harness adapter
3. Positive (+) probe to YELLOW wire
4. Negative (-) probe to ground
– Repeat test with the other two YELLOW/
BLACK wires of the 4-pin magneto harness
adapter.
NOTE: There should be no continuity (infinity) be-
tween the stator insulated coils and ground. If
there is a reading, the stator coils and/or the wiring
from the coils is grounded and needs to be re-
placed or repaired.
Dynamic Test (AC Voltage)
– Disconnect the voltage regulator/rectifier con-
nector.
– Disconnect the magneto wiring harness con-
nector.
– Install the 4-pin magneto harness adapter
(P/N 295 000 131) between connectors.
– Connect test probes of the multimeter to the
YELLOW and BLACK/YELLOW wires of the
4-pin magneto harness adapter.
– Start and rev engine to 3500 RPM. The obtained
valueshouldbebetween25and40Vac.
– If the battery charging coil is out of specification,
replace it.
