Electrical and Ignition
Stator Tests
98
Use a digital multimeter to measure sensor resis-
tance.
Knock Sensor Test
There are no tests for the knock sensor. If Evin-
rude Diagnostics reports Service Code 7 or 8,
replace with a new sensor.
Make sure sensor retaining screw is tightened to a
torque of 14 to 16 ft. lbs. (19 to 22 N·m).
Stator Tests
The stator consists of 3 windings (6 poles each)
on a 7 inch diameter core and generates an out-
put voltage of 55 VAC (1700 watts maximum).
This voltage is converted by the
EMM and used to
provide 12 VDC for battery charging (10 A at 500
RPM and 50 A from 2000 RPM to WOT) and 55
VDC for fuel injector, fuel and oil pump operation.
The ignition module of
EMM is also powered by
the 55 VDC output.
Stator Resistance Tests
Use a digital multimeter to check resistance of sta-
tor windings.
Disconnect EMM J2 connector from EMM .
Connect meter leads to the following pins:
•
Yellow/white and yellow (pins 17 and 7)
•
Brown/white and brown (pins 28 and 8)
•
Orange/white and orange (pins 18 and 10)
IMPORTANT:
A reading of less than 2 ohms is
acceptable. Make sure meter is calibrated to read
1 ohm or less.
To check for a grounded winding, connect one
meter lead to ground and alternately connect the
other meter lead to each stator wire. Meter should
