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. 84.
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. 88
• 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. 87
• Refer to Ignition Coil Tests on p. 87.
Voltages fluctuate, engine misfires:
• Inspect battery and connections
• Test capacitor and all ground connections.
• Refer to System Voltage Test on p. 84
• Refer to Ignition Control Circuit Tests on
p. 87
• Refer to Ignition Coil Tests on p. 87.
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. 66.
