ELECTRICAL AND IGNITION
CHARGING SYSTEM TESTS
Auxiliary Battery Charge Wire
The auxiliary battery charge feature requires aux-
iliary battery charge kit, P/N 5006253 (or equiva-
lent).
IMPORTANT:
Disconnect all accessories from
the auxiliary battery. Auxiliary battery must read a
minimum of 8.5 V at the beginning of these tests
and remain connected to the outboard during the
tests.
Check battery ground cable for continuity.
With the key switch OFF, check battery voltage at
auxiliary battery, then check voltage at auxiliary
battery connection. If the readings are not the
same, replace wire to auxiliary battery. The auxil-
iary battery wire must be at least 10-gauge and it
must be protected by a 50 A fuse or circuit
breaker at the battery.
With outboard running at 1000 RPM, voltage must
read higher than with key OFF and increase
steadily to approximately 14.5 V as the outboard
RPM increases.
If there is no increase, turn the key switch to OFF
and test red/black wire between the
EMM and
auxiliary battery connection.
•
Continuity indicates faulty output from EMM .
Check 12 V alternator output before replacing
EMM for faulty auxiliary battery, charge isolator
circuit.
•
No continuity indicates faulty wiring.
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 J2 connector
of
EMM . Voltage at EMM connector should be
approximately 30 V.
With outboard running at 1000 RPM, voltage on
white/red wires should increase to 55 V. Voltage
readings at a specific speed (RPM) should be
steady.
If there is any other reading, refer to STATOR
TESTS on p. 96. Inspect the stator wiring and
connections. Inspect the capacitor wiring, connec-
tions, and capacitor. Repair the wiring or replace a
faulty capacitor, stator, or
EMM .
