Stator Tests - BRP Evinrude E-TEC Series Service Manual

STATOR TESTS

The stator consists of 2 windings (6 poles each)
on a 5 inch diameter core and generates an out-
put voltage of 55 VAC (700 watts maximum). This
voltage is converted by the Battery Charge Mod-
ule to provide 12 VDC for battery charging
(approximately 8 A at 500 RPM and 15 A from
3000 RPM to WOT) and 55 VDC for fuel injector,
and fuel and oil pump operation.
Stator Resistance Tests
Use a digital multimeter to check resistance of sta-
tor windings.
Disconnect stator (4-pin) connector from the
engine harness (4-pin) connector.
Stator Winding Resistance Specification
Yellow & Yellow / white

1. Stator connector
Connect meter leads to the following pins:
•
Yellow/white and yellow (pins 1 and 2)
•
Brown/white and brown (pins 3 and 4)
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
E S
LECTRIC TART
Use a digital multimeter to check stator output
voltage. Set meter to read 110 VAC output.
WARNING
To prevent accidental starting of outboard,
disconnect crankshaft position sensor
(CPS).
Disconnect CPS.
Disconnect stator (4-pin) connector from the
engine harness (4-pin) connector.
Connect Stator Test Adaptor tool, P/N 354719, to
stator connector.
Connect meter leads to terminals of adaptor tool.
With a fully charged battery, crank outboard (300
RPM minimum) and observe meter reading:
•
55 VAC above 500 RPM
