Ignition Voltage Test; Static Ignition Test - BRP E250DHLSCS Service Manual

Ignition Voltage Test

Use the Evinrude Diagnostics software Monitor
screen to check ignition voltage to the primary
ignition circuits of the ignition coils.
Engine Monitor Screen, Ignition Voltage
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:
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.

Testing, Static Test Screen
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.
