Voltage Test
Proceed as follows:
– Start engine.
– Connect a multimeter to battery posts. Set mul-
timeter to Vdc scale.
– Bring engine to approximately 5500 RPM.
If multimeter reads over 15 volts, regulator is de-
fective. Replace it.
NOTE: If it is continually necessary to add distilled
water to the battery, this indicates an over voltage
situation, requiring replacement of the rectifier/
regulator. If, on the other hand, the battery will not
stay charged, the problem can be any of the
charging circuit components. If these all check
good, you would be accurate in assuming the
problem to be in the rectifier/regulator.
SPX, GS, GTS and GTI Models
If there is no charging at the battery with the pre-
ceding voltage test, the following test can also be
performed.
SPX and GTS Models
Open the electrical box.
Disconnect the RED and BLACK wires of the rectifier/
regulator.
GS and GTI Models
Disconnect the connector housing of the rectifier/
regulator.
Using an appropriate terminal remover (Snap-on
TT600-4), remove the RED and BLACK wires from
the tab housing of the rectifier/regulator.
Reconnect the connector housing.
SPX, GS, GTS and GTI Models
Connect the positive probe of a multimeter to the
RED wire and the negative probe to the BLACK
wire.
Set multimeter to Vdc scale.
Start and rev engine to 3500 RPM. The obtained
value should be between 12 and 25 Vdc.
NOTE: If the rectifier/regulator is within the speci-
fication, either the MPEM or wiring harness be-
tween the rectifier and battery is defective. If the
rectifier/regulator is out of specification and the bat-
tery charging coil (or stator) test good, the rectifier/
regulator is defective.

STATIC TEST: CONTINUITY
1. Disconnect the magneto wiring harness con-
nector.
2. Install the 4-pin magneto harness adapter (P/N
295 000 131).
3. Check resistance between the YELLOW and
YELLOW/BLACK wires of the magneto har-
ness adapter. Refer to the following table.
NOTE: A short circuit will read 0 ohm (or close to)
on ohmmeter.
1. Multimeter
2. Magneto harness adapter
3. YELLOW and YELLOW/BLACK wires
DYNAMIC TEST
1. Disconnect the magneto wiring harness con-
nector.
2. Install the 4-pin magneto harness adapter (P/N
295 000 131).
3. Connect test probes of the multimeter to the
YELLOW and YELLOW/BLACK wires of the 4-pin
magneto harness adapter.
4. Start and rev engine to 3500 RPM. The ob-
tained value should be between 25 and 40 Vac.
5. If the battery charging coil is out of specifica-
tion, replace it.
