OILING SYSTEM TESTS
IMPORTANT:
Always perform visual inspec-
tions to identify oiling system leaks. Make sure the
oil tank is filled and oil supply is not contaminated.
Oil Injection Pump Static Test
IMPORTANT:
Static tests are performed with
the outboard not running.
Use
Evinrude Diagnostics
software to activate the
Oil Injector
test. This test starts the
EMM
control
function for the oil injection pump.
The
EMM
controls the pump by providing ground
through pin 23 (blue wire) of the J1-B connector
and pin 2 (blue wire) of the oil tank connector.
IMPORTANT:
This test is operating the pump
with 30 V on the system voltage (55 V) circuit. The
start assist circuit (SAC) of the
EMM
converts bat-
tery voltage (12 V) to 30 V of system voltage. Bat-
tery must be fully charged and connections must
be clean and tight. Pump activation should be
carefully confirmed.
Use an inductive timing light to monitor current
flow through the ground circuit (blue wire) at the
oil tank connector (pin 2).
If the light flashes, the
EMM
and oil injection cir-
cuits are not at fault.
Refer to
Oil Injection Pump Voltage Test
on
p. 195.
Oil Injection Pump Voltage Test
Check voltage at pin 1 (white/red wire) of oil tank
electrical connector.
Acceptable voltage readings:
•
Key switch ON: approximately 30 V
•
Outboard running: 55 V
Results:
•
If voltage is not within range, refer to
Oil Injec-
tion Pump Circuit Resistance Test
on p. 196.
•
No voltage reading, refer to
System Voltage
Test
on p. 116.
Monitor the voltage on the oil injector circuit at
pin 2 (blue wire) of oil tank connector with out-
board running at 1500 RPM.
Use an appropriate test probe and a digital multi-
meter calibrated to a scale that reads 55 V (DC).
Connect positive meter lead to pin 2 and negative
meter lead to ground.
Voltage reading should be approximately 55 V,
and drop approximately 5 V as
EMM
actuates oil
injection pump.
