Symptoms - BRP Evinrude E-Tec Series Service Manual

Symptoms

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 B+ is present at "A" terminal (pur-
•
ple wire) of starter solenoid with key switch in
the ON position.
Proceed to START CIRCUIT on p. 122. Repair
•
starter or start circuit as needed.
Outboard cranks, will not start:
Use LED indicators of EMM for initial diagnostic
•
information.
Perform a spark test using the Evinrude Diag-
•
nostics Software program. Refer to IGNITION
OUTPUT on p. 127.
Results:
Steady spark on all cylinders and proper ignition
voltage:
Check operation of all fuel injectors. Refer to
•
FUEL COMPONENT TESTS on p. 184.
Check fuel quality and that fuel is present at
•
injectors.
Refer to FUEL COMPONENT TESTS on p. 184
•
for fuel system pressure tests.
No spark on one or more cylinders:
Note cylinder with no ignition output. Refer to
•
IGNITION OUTPUT on p. 127.
Monitor cranking RPM using the diagnostic pro-
•
gram (approximately 175 RPM, minimum 75
RPM).
Check CPS operation (verify RPM reading.)
•
Perform ignition circuit resistance test(s). Refer
•
to Ignition Primary Circuit Resistance Test
on p. 130 and IGNITION COIL TESTS on
p. 141.
DIAGNOSTIC PROCEDURES
Outboard runs:
Use Evinrude Diagnostics Software program to
•
perform Dynamic Tests. See Dynamic Tests on
p. 133.
Use the engine Monitor screen of the Evinrude
•
Diagnostics Software program to observe circuit
voltages. Refer to Engine Monitoring Informa-
tion on p. 121.
Use the diagnostic software Logging function to
•
record engine data as a runability problem is
occurring.
Logging Screen
Use an inductive timing light to monitor the
•
injector circuits and ignition primary circuits.
Refer to Testing with Timing Light on p. 120,
IGNITION OUTPUT on p. 127, FUEL DELIV-
ERY on p. 131 and FUEL COMPONENT
TESTS on p. 184.
Use an inductive amp meter to monitor injector
•
circuit current. Compare readings of all circuits
to identify possible failure.
