System Analysis
Ignition Output Tests
86
The outboard must NOT be running and the emer-
gency stop switch lanyard must be installed.
Connect timing light pickup to the secondary cir-
cuit (spark plug lead) of the cylinder being tested.
Activate test and observe timing light strobe for
consistent flash.
IMPORTANT:
You may need to remove shield-
ing from wire if pickup does not read signal.
Results:
No spark on one or more cylinders:
•
Inspect or replace spark plugs
•
Refer to Ignition Control Circuit Tests on
p. 87
•
Refer to Ignition Coil Tests on p. 87.
Steady spark on all cylinders:
•
Refer to Running Ignition Tests on p. 86 and
Dynamic Tests on p. 79.
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. 85.
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. 82.
•
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. 85
•
Refer to Ignition Control Circuit Tests on
p. 87.
•
Refer to Ignition Coil Tests on p. 87.
