7. Set an ohmmeter to Rx1 scale and zero meter. Test
ignition/key switch as follows.
a. Trace two black leads from on/off switch and
separate them from any connections. Connect
ohmmeter leads to switch leads, and check for
continuity in both switch positions.
Condition Conclusion
Continuity should be
indicated when and only
when switch is in OFF
position.
Replace switch for any
other results.
b. On electric start engines, trace four leads (red,
red/white, black, black/white) from key switch and
separate them from any connections. Connect
ohmmeter leads to black and black/white leads
and check for continuity in all three switch
positions. Then connect ohmmeter leads to red
and red/white leads and test again in all three
switch positions.
Condition Conclusion
Continuity should be
indicated between black
and black/white leads only
when key switch is in OFF
position. There should be
continuity between red
and red/white leads only
in start position.
Replace switch for any
other results.

NOTE: Observe following guidelines to avoid damage to
electrical system and components:
● Make sure battery polarity is correct. A negative (-)
ground system is used.
● Make sure all ground connections are secure and in
good condition.
● Disconnect both battery cables before doing electrical
welding on equipment powered by engine. Also,
disconnect other electrical accessories in common
ground with engine.
● Prevent stator (AC) leads from touching or shorting
while engine is running. This could damage stator.
Most engines are equipped with a 3,4,10, or 18 amp
regulated battery charging system.
3/4/10/18 Amp Regulated Charging System
Stator
Stator is mounted on crankcase behind fl ywheel.
Should stator have to be replaced, follow procedures in
Disassembly.
Rectifi er-Regulator
NOTE: When installing recti fi er-regulator, push wiring
harness plug into regulator receptacle until it
locks into place.
Recti fi er-regulator is connected to engine with a
matching wiring harness containing a plug-in connector.
Grounded through wiring harness, recti fi er-regulator
is secured to equipment in a suitable location with two
mounting screws. To replace it, disconnect plug, and
remove two mounting screws.
Recti
fi er-regulator converts AC voltage coming from
stator to DC voltage, while also monitoring and
controlling battery voltage. There are two different
recti fi er-regulators which are used; an 18 amp and a
10 amp assembly. Although externally similar, internal
circuits differ and two should not be interchanged.
Rectifi ed Only (non-regulated) Systems
Some engines are equipped with a recti fi ed only, non-
regulated charging system, with output ranging from
3 amps to 4 amps. Recti fi er is normally connected to
engine with a matching wiring harness and secured
inside control panel. Grounding is achieved through
wiring harness. Recti fi er converts AC voltage coming
from stator to DC voltage only.
