ELECTRICAL AND IGNITION
STATOR TESTS
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
stator 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
read no continuity. If meter reads continuity,
replace stator.
Stator Voltage Output Test
Use a voltmeter to check the stator output voltage.
Set meter to read 110 VAC output.
Disconnect CPS.
Disconnect stator (6-pin) connector from the
engine harness (6-pin)
connector.
Connect Stator Test Adaptor tool, P/N 5006211,
to stator connector.
Connect meter leads to terminals of adaptor tool.
With a fully charged battery, crank outboard (100
RPM minimum) and observe meter reading:
•
20 VAC at 100 RPM
•
30 VAC at 150 RPM
•
42 VAC at 200 RPM
•
52 VAC at 250 RPM
•
62 VAC at 300 RPM
Stator Winding Resistance
Yellow & Yellow / white
.512 ± .020
@ 73°F (23°C)
Brown & Brown / white
.512 ± .020
@ 73°F (23°C)
Orange & Orange / white
.512 ± .020
@ 73°F (23°C)
