Static Tests
Ignition System Static Test
Perform the static ignition test using Evinrude
Diagnostics software and an inductive timing light.
IMPORTANT:
DO NOT use a spark checker tool.
Radio Frequency Interference (RFI) generated by
the arcing current can cause erratic
EMM opera-
tion.
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 Circuit Tests on p. 123
•
Refer to Ignition Coil Tests on p. 123.
Steady spark on all cylinders:
•
Refer to Running Ignition Tests on p. 122 and
Dynamic Tests on p. 108.
Fuel System Static Tests
Fuel Pump Static Test
Use the Evinrude Diagnostics software Fuel Pump
test to activate the electric fuel pump. If the pump
runs, the
EMM and fuel pump circuit are not at
fault.
If the pump does not run:
•
The EMM controls power to the fuel pump (pur-
ple/black wire). Check voltage at pin 1 of fuel
pump connector. Voltage should be 12 V when
KEY is first ON, when fuel pump test activated,
or when outboard is cranking or running.
•
Use an ohmmeter to check continuity between
pin 2 of fuel pump connector and ground.
•
Refer to Fuel Circulation Pump Resistance
Test on p. 166.
If the pump runs:
•
Refer to Fuel System Pressure Tests on
p. 160.
•
Refer to Running Fuel System Tests on
p. 160.
