Oiling System Tests
IMPORTANT:
Always perform visual inspections
to identify oiling system leaks. Make sure the oil
tank is filled and oil supply is not contaminated.
Oil Injection Pump Static Test
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 pump connector.
Use Evinrude Diagnostics software to activate the
Oil Injector test. This test starts the EMM control
function for the oil injection pump.
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. Listen for an audible click from
the oil injection pump when it is activated.
Use an inductive timing light to monitor current
flow through the ground circuit (blue wire) at the
oil pump connector (pin 2).
If the light flashes, the EMM and oil injection cir-
cuits are not at fault.
Refer to Oil Injection Pump Voltage Tests on
p. 178.
Oil Injection Pump Voltage Tests
Use a digital multimeter calibrated to a scale that
reads 55 V (DC) to measure voltage between the
oil pump electrical connector and engine ground.
Connect negative meter lead to ground.
Use an appropriate test probe to connect positive
meter lead to pin 2 (blue wire) of oil injection pump
electrical connector.
Turn the key switch to the ON position. Observe
voltage at pin 2.
•
Voltage at pin 2 should be approximately 30 V.
