Troubleshooting

Outboard will not crank, starter does not
operate:
Check condition of battery and cables (main
•
battery switch and cables). Make sure battery
cables are not reversed.
Confirm that switched B+ is present at "A" termi-
•
nal (purple wire) of starter solenoid with key
switch in the ON position.
Refer to ELECTRIC START TESTS on p. 137.
•
Repair starter or start circuit as needed.
Outboard cranks, will not start:
Check emergency stop switch and lanyard
•
Check powerhead mounted neutral switch
•
Check the EMM LED Indicators for system sta-
•
tus information. Refer to EMM LED INDICA-
TORS on p. 113.
Use the Evinrude Diagnostics software Stored
•
Faults screen to check for current service
codes. If there are multiple stored sensor
codes, inspect all 5 V sensor circuits for broken
or grounded wiring.
Perform a Static Ignition test using Evinrude
•
Diagnostics software and an inductive timing
light. Refer to Static Ignition Test on p. 117.
If ignition test indicates steady spark, refer to
•
FUEL DELIVERY TESTS on p. 120.
Outboard runs, low on power, misfires:
Check the EMM LED Indicators for system sta-
•
tus information. Refer to EMM LED INDICA-
TORS on p. 113.
Use the Evinrude Diagnostics software Monitor
•
screen to check system (55 V), ignition (200 V),
and TPS voltages. System and ignition voltage
should be steady, and TPS voltage should be
between 0.2 and 4.85 V.
DIAGNOSTIC PROCEDURES
Use the diagnostics software Dynamic Tests to
•
isolate a faulty cylinder. See DYNAMIC TESTS
on p. 112.
Use an inductive timing light to check ignition
•
and fuel injector circuits. Refer to Running Igni-
tion Tests on p. 118 and Running Fuel Sys-
tem Tests on p. 121.
Use the diagnostics software Fuel Control
•
Adjustment test to help identify a cylinder that
may be too rich or too lean. Refer to Fuel Con-
trol Adjustment on p. 112.
Use an inductive amp meter to monitor injector
•
circuit current. Compare readings of all circuits
to identify possible failure.
Check fuel quality and that fuel is present at
•
injectors.
Use the diagnostics software Logging function
•
to record engine data as a problem is occurring.
Logging Screen
Use a digital multimeter to check
IMPORTANT:
voltage on external circuits only when necessary.
All EMM output currents are DC current.
