OILING SYSTEM
OILING SYSTEM TESTS
Use the Oil Injector test of Evinrude Diagnostic
software Static Test screen to activate the oil
pump.
IMPORTANT:
This test is operating the pump
with 12 V battery power on the system voltage
(55 V) circuit. The oil injection pump will not pump
oil when operating on 12 V.
Observe voltage at pin A.
•
Voltage at pin A should drop as the oil pump
cycles.
Check the control signal while the Oil Injector test
is running. Set the digital multimeter to the Hertz
(Hz) scale.
•
Meter should read approximately 1.2 Hz.
Results:
•
If voltage and control signal readings at pin A
are within range, the
EMM and wiring are not at
fault.
•
If voltage at pin A is not within range, check volt-
age at pin B (white/red wire) of oil pump electri-
cal connector.
Connect positive meter lead to pin B (white/red
wire) of oil injection pump electrical connector.
Observe voltage at pin B.
•
Voltage at pin B should be approximately 12 V.
Set digital multimeter to a scale that reads 55 V
(DC).
Start the engine. Observe voltage at pin B.
•
Voltage at pin B should be approximately 55 V.
•
If voltage at pin B is within range, refer to Oil
Injection Pump Resistance Test on p. 152.
•
No voltage reading at pin A, refer to System
Voltage Test on p. 74.
Oil Injection Pump Resistance
Test
Disconnect the battery cables at the battery.
Disconnect the electrical connector from the oil
injection pump.
Use a digital multimeter to measure the resistance
between the pins of the oil injection pump connec-
tor. Calibrate the meter to the LOW OHMS scale.
Results:
•
An infinite reading (

) indicates an open circuit
of the injection pump winding. Replace faulty
pump.
