Running Ignition Tests

The purpose of this test is to isolate ignition sys-
tem malfunction. This test should be used in con-
junction with other ignition system tests to identify
component failures. This test provides limited
information. Use the findings of this test to elimi-
nate ignition system components. A thorough
understanding of the outboard's ignition system is
required.
Monitor Voltage Outputs
Use the Evinrude Diagnostics Software program
to monitor system voltage (55 V) and ignition volt-
age (200 V).
Voltage readings at a specific speed (RPM)
•
should be steady.
Engine Monitor Screen, System and Ignition Voltage
Results:
Low voltages: refer to System Voltage on p. 128
and Ignition Voltage on p. 127.
Monitor Ignition Output with Timing Light
Use a timing light to monitor the spark signal
through each of the high tension spark plug wires.
Start outboard and observe the timing light's
strobe. Look for a consistent flash and only one
flash per revolution. The strobe of the timing light
should be consistent or the same for each cylin-
der's ignition output.
IMPORTANT:
from secondary circuit appears faulty.

Results:
Steady voltage and strobe:
Inspect or replace spark plugs, check fuel sys-
•
tem performance, and / or eliminate the possi-
bility of internal engine damage.
Voltages are steady, engine misfires:
Check CPS air gap and resistance, check igni-
•
tion voltage while problem is occurring. See
Ignition Primary Circuit Resistance Test on
p. 130 and IGNITION COIL TESTS on p. 141.
Voltages fluctuate, engine misfires:
Inspect condition of battery and connections,
•
test capacitor, and check all ground connec-

tions. See System Voltage on p. 128, Ignition
Voltage on p. 127, Ignition Primary Circuit
Resistance Test on p. 130 and IGNITION COIL
TESTS on p. 141.
IMPORTANT:
about 1200 RPM, the outboard may be in S.A.F.E.
Refer to Conditions that initiate S.A.F.E. on
p. 103.
