Crankshaft Position Sensor (Cps) Test; System Voltage Test - Evinrude E-TEC 200 Service Manual

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.
Engine Monitor Screen, Engine RPM display
If the Monitor screen says "Check CPS Sync,"
refer to Crankshaft Position Sensor (CPS) Test
on p. 94.

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.
008104
•
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
output to EMM. Repair connection or wiring.
Possible faulty stator or EMM. Refer to STATOR
TESTS on p. 96.
IMPORTANT:
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.
