SYSTEM ANALYSIS
IGNITION OUTPUT TESTS

Running Ignition Tests
Use
Evinrude Diagnostics
software to monitor
system voltage (55 V).
•
Voltage readings at a specific speed (RPM)
should be steady.
•
Refer to
System Voltage Test
on p. 119.
Use an inductive timing light to monitor the spark
signal through each of the secondary circuit
(spark plug lead) wires.
Start outboard and observe timing light strobe.
Look for a consistent flash and only one flash per
revolution. The strobe of the timing light should be
the same for each cylinder.
Results:
Steady voltage and strobe, engine misfires:
•
Inspect or replace spark plugs
•
Refer to
FUEL DELIVERY TESTS
on p. 123.
•
Check for internal engine damage.
Steady voltage, erratic strobe, engine misfires:
•
Inspect or replace spark plugs
•
Check CPS air gap and resistance.
•
Refer to
Ignition Control Circuit Tests
on
p. 122.
•
Refer to
Ignition Coil Tests
on p. 122.
Voltages fluctuate, engine misfires:
•
Inspect battery and connections
•
Test capacitor and all ground connections.
•
Refer to
System Voltage Test
on p. 119
•
Refer to
Ignition Control Circuit Tests
on
p. 122.
•
Refer to
Ignition Coil Tests
on p. 122.
IMPORTANT:
If a running problem occurs at
about 1200 RPM, the outboard may be in
S.A.F.E.
Refer to
S.A.F.E. WARNING SYSTEM
on p. 102.
