ELECTRICAL AND IGNITION

CHARGING SYSTEM TESTS

STEP 2
To check for a grounded condition, connect one
meter lead to ground wire and alternately connect
the other meter lead to each stator wire. Meter
should read no continuity. If meter reads continu-
ity, replace stator due to grounded winding.
Stator Voltage Output Test
Use a voltmeter to check the 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 (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.

1. Stator Test Adaptor
With a fully charged battery, crank outboard (100
RPM minimum) and observe meter reading.

CHARGING SYSTEM
TESTS
12 V Charging Circuit
To test the operation of the regulator in the EMM,
you must be able to run the outboard continuously
at approximately 5000 RPM, such as in a test tank
or on a marine dynamometer.
The test consists of monitoring the system's
response to a partially discharged battery. Use a
variable load tester to discharge the battery.
IMPORTANT:
voltage on the red wire to operate. Before pro-
ceeding, make sure battery voltage is at the con-
nector red wire when key is ON.
Test Procedure
Disconnect the battery cables at the battery.
Use an inductive amp meter or connect a 0 to
50 A ammeter in series between the red wire(s) of
engine wire harness (alternator output from EMM)
and the positive (B+) battery cable terminal of
starter solenoid.
IMPORTANT:
charging. Each output is isolated and regulated.
Each output is 25 A. Combined output is approxi-
mately 50 A. Refer to engine wiring diagram.

Fluke
or EETA501, and various other amp meters
should be available through local tool suppliers.
Reconnect the outboard's battery cables.
