Use the
Oil Injector
te st o f
Evinrude Diagnostic
software
Static Test
screen to activate the oil
pump.
IMPORTANT:
This test is op erating the pump
with 12 V b attery power o n the system volt age
(55 V) circuit. The oil injection pump will not pump
oil when operating on 12 V.
Observe voltage at pin B.
•
Voltage at pin B should drop as the oil pump
cycles.
Check the control signal while the
Oil Injector
test
is running. Set the digit al multimeter to the Hertz
(Hz) scale.
•
Meter should read approximately 5 Hz.
Results:
•
If volt age an d con trol signal readings at pin B
are within range, the
EMM
and wiring are not at
fault.
•
If voltage at pin B is not within range, check volt-
age at pin A (white/red wire) of oil pump electri-
cal connector.
Connect positive meter lead to pin A (white /red
wire) of oil injection pu mp electrical connector.
Observe voltage at pin A.
•
Voltage at pin A should be approximately 12 V.
Set digital multimeter to a scale that re ads 55 V
(DC).
Start the engine. Observe voltage at pin A.
•
Voltage at pin A should be approximately 55 V.
•
If volt age at p in A is within range, refer to
Oil
Injection Pump Resistance Test
on p. 167.
•
No volt age re ading at pin A, refe r to
System
Voltage Test
on p. 80.
Oil Injection Pump Resistance
Test
Disconnect the battery cables at the battery.
Disconnect the electrical conn ector 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 th e injection pump winding. Replace faulty
pump.
