CHARGING SYSTEM TESTS

Start and run the outboard at approximately 5000
RPM. Use the variable load tester to draw the bat-
tery down at a rate equivalent to the stator’s full
output.
•
The ammeter should indicate nearly full output,
approximately 15 A @ 5000 RPM.
Note: When the battery charge module is at full
load, it is normal for the 55 V circuit to experience
a voltage drop of up to 2 VDC.
Decrease the battery load toward 0 A.
•
Ammeter should show a reduced output. As the
current draw decreases, the battery voltage
should stabilize at approximately 14.5 V.
•
If results vary, check stator and alternator circuit
BEFORE replacing the battery charge module.
Refer to
STATOR TESTS on p. 89 and 55 V
Alternator Circuit on p. 93.
55 V Alternator Circuit
Check battery ground cable for continuity.
With the key switch ON, check battery voltage at
battery (12 V).
Then, use Electrical Test Probe Kit, P/N 342677,
and a digital multimeter set to read 55 VDC to
check voltage on white/red wires at the
EMM con-
nector. Voltage at EMM connector should be 0.5
to 1 V less than battery.
With outboard running at 1000 RPM, voltage on
white/red wires should be 55 V. Voltage readings
at a specific speed (RPM) should be steady.
If there is any other reading, refer to STATOR
TESTS on p. 89. Inspect the stator wiring and
connections. Repair the wiring or replace a faulty
stator, or
EMM .
