OILING SYSTEM TESTS
IMPORTANT: Always perform visual inspections
to identify oiling system le aks. Ma ke sure t he oil
tank is filled and oil supply is not contaminated.
Oil Injection Pump Static Test
The EMM controls the pu mp by providing grou nd
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 st arts the EMM control
function for the oil injection pump.
IMPORTANT: This test is op erating 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 cha rged and connections must
be clean and tight. Pump activation sho uld be
carefully confir med. Listen for an audible click
from the oil injection pump when it is activated.
Use an ind uctive timing lig ht to monitor cu rrent
flow throu gh the groun d circu it (blue wire) at the
oil pump connector (pin 2).
If the lig ht flashes, the EMM and oil in jection cir-
cuits are not at fault.
Refer to Oil Inje ction Pump V oltage Tests on
p. 173.
Oil Injection Pump Voltage Tests
Use a digital multimeter calibrated to a scale that
reads 55 V (DC) to mea sure 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 th e key switch to the ON positio n. Observe
voltage at pin 2.
• Voltage at pin 2 should be approximately 30 V.
