IGNITION OUTPUT TESTS

Ignition Voltage Test
Use the
Evinrude Diagnostics
software
Monitor
screen to check ignition voltage to the primary
ignition circuits of the ignition coils.
Results:
•
KEY ON (not running) - 125 V ± 10, Ignition
voltage is GOOD, check voltage with outboard
running.
•
KEY ON (not running) - less than 125 V ± 10,
check system voltage to
EMM.
Refer to
System
Voltage Test
on p. 116
.
Note: Key ON voltage
will not be constant (fluctuates 125 - 200 V
range)
•
“RUNNING” - 200 V ± 10, Ignition voltage is
GOOD.
•
“RUNNING” - less than 200 V ± 10, check stator
output to
EMM
. Refer to
System Voltage Test
on p. 116 and
STATOR TESTS
on p. 132
Low or no voltage on
EMM
ignition circuit:
•
Check system voltage (55 V) input to ignition
circuit on pin 4 of
EMM
J1-B connector.
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 Inter-
ference (RFI) generated by the arcing current can
cause erratic behavior in the
EMM
.
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.
