Static Ignition Test
Perform the static ignition test using
Evinrude
Diagnostics
software and an inductive timing light.
IMPORTANT:
DO NOT use a spark checker tool
with
E-TEC
models. Radio Frequency Interfer-
ence (RFI) generated 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.
IMPORTANT:
Diagnostic communications on
non-running rope start models requires that power
is supplied to the
EMM
. Refer to Communication
on p. 95.
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. 113
