Electrical and Ignition
Ignition System

Wiring Inspection

Visually inspect all wiring, connections, and
grounds.
Use a digital ohmmeter to test resistance on all
ground circuits and connections. Ohmmeter read-
ings should be approximately 0.0 Ω.
Check that all engine wire harness grounds have
continuity to the cylinder/crankcase. See Ground
Circuits on p. 115.
Clean or repair all ground circuits, wiring, and con-
nections as needed.

Ignition System Tests

NOTICE
Use appropriate test leads or adapters such
as Test Probe Kit, P/N 342677, when perform-
ing electrical tests.
NEVER pierce the insulation of the engine
wiring, or use any piercing-style test probe.
Piercing insulation damages the wire and can
cause other unintended electrical problems.
Before continuing make sure the CPS is operat-
ing. Refer to Crankshaft Position Sensor (CPS)
Operation Test on p. 117. If the Monitor screen
says "Check CPS Sync," refer to Crankshaft
Position Sensor (CPS) Resistance Test on
p. 117.
System Voltage Test
The ignition system is powered by the 55 V sys-
tem.

Use the Evinrude Diagnostics software Monitor
screen to check system voltage.

Results:
•
EMM ON (not running): 30 V ± 2, system volt-
age is GOOD.
•
EMM ON (not running): less than 30 V ± 2,
check 12 V power to EMM. Repair connection
or wiring. Possible fault in EMM SAC circuit.
•
RUNNING: 55 V ± 2, system voltage is GOOD.
•
RUNNING: less than 55 V ± 2, check stator out-
put to EMM. Repair connection or wiring. Possi-
ble faulty stator or EMM. Refer to Stator Tests
on p. 125.
IMPORTANT:
The EMM must be ON for voltage
to be present on the system voltage (55 V) circuit.
Power is normally supplied to the EMM when the
key switch is turned ON. The EMM is also turned
ON when it begins to receive AC voltage from the
stator while the outboard is being cranked.
Running Ignition Tests
Use Evinrude Diagnostics software to monitor
system voltage (55 V).
•
Voltage readings at a specific speed (RPM)
should be steady.
•
Refer to System Voltage Test on p. 122.
Use an inductive timing light to monitor the spark
signal through each of the secondary circuit
(spark plug lead) wires.
Start outboard and observe timing light strobe.
Look for a consistent flash and only one flash per
