clear the codes FIRST.

Required Ignition Systems

Following is a complete list of circuits required for
ignition output:

Stop Circuit
•

Black/yellow wire NOT grounded (emergency
stop switch lanyard in place).

Neutral Switch
•

Powerhead mounted neutral switch provides a
switched ground circuit to

EMM

. The circuit

enables specialized control functions such as
neutral start protection and RPM limiting in
NEUTRAL.

Stator Output Voltage
•

Provides A/C voltage to

EMM

J2 connector:

Outboard cranking, typical range is 20-40 VAC
(AC output voltage is related to cranking RPM

)

;

Outboard running, approximately 55 VAC.

EMM

•

Controls

ignition grounds, injector grounds, and

engine timing.

Crankshaft Position Sensor
•

Provides

EMM

with input.

DANGER

The electrical system presents a serious
shock hazard. Allow outboard to sit for two
minutes after running before handling capaci-
tor or 55 V electrical components. Failure to
handle capacitor properly can result in
uncontrolled electrical discharge and possi-
ble electrical shock to humans.

DO NOT handle primary or secondary igni-
tion components while outboard is running
or flywheel is turning.
