SYSTEM ANALYSIS
IGNITION OUTPUT TESTS
Crankshaft Position Sensor (CPS)
Test
When the CPS is working proper ly,
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 outboa rd 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. 95.
System Voltage Test
The ignition system is p owered by the 55 V sys-
tem.
Use th e
Evinrude Diagnostics
so ftware
Monitor
screen to check system voltage.
Results:
•
EMM
ON (not running) - approximately 1 V less
than battery voltage, system voltage is GOOD.
•
EMM
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 tha n 55 V ± 2, check st ator
output to
EMM
. Rep air connection o r wirin g.
Possible faulty stator or
EMM.
Refer to
STATOR
TESTS
on p. 97.
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 turn ed
ON when it begins to receive AC voltage from the
stator while the outboard is being cranked. On a
non-running rope st art engine, power is supplied
to the
EMM
by Diag nostic Power Supply T ool,
P/N 587005.
