Static Ignition Test
Perform the static ignition test using Evinrude
Diagnostics software and an inductive timing light.
IMPORTANT: DO NOT perform static tests
using Diagnostic Power Supply Tool, P/N 587005,
with internal 9 volt batteries only. This will produce
false results. Refer to Communication on p. 67.
IMPORTANT: DO NOT use a spark checker
tool. Radio Frequency Interference (RFI) gener-
ated by the arcing current can cause erratic EMM
operation.
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: This test is operating the ignition
coil with 12 V battery power on the system voltage
(55 V) circuit. An inductive probe with low sensitiv-
ity may not be able to detect the 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. 80.
