DIAGNOSTIC PROCEDURES
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. 140.
•
Repair starter or start circuit as needed.
Outboard cranks, will not start:
Check emergency stop switch and lanyard
•
Check the EMM LED Indicators for system sta-
•
tus information. Refer to EMM LED INDICA-
TORS on p. 116.
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. 120.
If ignition test indicates steady spark, refer to
•
FUEL DELIVERY TESTS on p. 123.
Outboard runs, low on power, misfires:
Check the EMM LED Indicators for system sta-
•
tus information. Refer to EMM LED INDICA-
TORS on p. 116.
Use the Evinrude Diagnostics software Monitor
•
screen to check system (55 V) and TPS volt-
ages. System voltage should be steady, and
TPS voltage should be between 0.2 and 4.85 V.
Use a digital multimeter to check
IMPORTANT:
voltage on external circuits only when necessary.
All EMM output currents are DC current.

Use the diagnostics software Dynamic Tests to
•
isolate a faulty cylinder. See DYNAMIC TESTS
on p. 115.
Use an inductive timing light to check ignition
•
and fuel injector circuits. Refer to Running Igni-
tion Tests on p. 121 and Running Fuel Sys-
tem Tests on p. 124.
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. 115.
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
AFTER all the above inspections, if the cause of
•
a running quality problem still cannot be identi-
fied, perform a compression test to check for
internal powerhead damage.
Remove a cylinder head or disas-
IMPORTANT:
semble the engine only as a last resort.
