SYSTEM ANALYSIS
IGNITION OUTPUT TESTS
Crankshaft Position Sensor (CPS)
Test
When the CPS is working properly,
EMM
LED 2
turns on while the outboard is being started.
Use the
Evinrude Diagnostics
software CPS Sync
and engine RPM displays to confirm a valid CPS
signal while the outboard is cranking or running.
An RPM display higher than zero indicates a CPS
signal to the
EMM
.
If the
Monitor
screen says “Check CPS Sync,”
refer to Crankshaft Position Sensor (CPS) Test
on p. 124.
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:
•
KEY ON (not running) - approximately 1 V less
than battery voltage, system voltage is GOOD.
•
KEY ON (not running) - no voltage, check 12 V
power to
EMM.
Repair connection or wiring.
•
RUNNING - 55 V ± 2, system voltage is GOOD.
•
RUNNING - less than 55 V ± 2, check stator
output to
EMM
. Repair connection or wiring.
Possible faulty stator or
EMM.
Refer to STA-
TOR TESTS on p. 126.
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.
