Auxiliary Battery Charge Wire

The auxiliary battery charge feature requires aux-
iliary battery charg e kit, P/N 500625 3 (or equiva-
lent).
IMPORTANT:
Disconnect all accessories fro m
the auxiliary battery. Auxiliary battery must read a
minimum of 8.5 V at the beginning of these tests
and remain connected to th e outboard during the
tests.
Check battery ground cable for continuity.
With the key switch OFF, check battery voltage at
auxiliary battery , th en che ck voltage at auxilia ry
battery conne ction. If the rea dings are no t the
same, replace wire t o auxiliary ba ttery. The auxil-
iary battery wire must be at least 10-ga uge and it
must be prote cted by a 50 A fuse
breaker at the battery.

With outboard running at 1000 RPM, voltage must
read higher than with
steadily t o appr oximately 1 4.5 V as the outboard
RPM increases.
If there is no increase, turn the key switch to OFF
and test red/black wire
auxiliary battery connection.

Continuity indicates fa ulty ou tput from EMM.
Check 12 V altern ator ou tput before replacin g
EMM for faulty auxiliary b attery, charge isolator
circuit.
•
No continuity indicates faulty wiring.

55 V Alternator Circuit

Check battery ground cable for continuity.
With the key switch ON, che ck battery voltage at
or circuit battery (12 V).
Then, use Ele ctrical Test Probe Kit, P/N 342677,
and a dig ital multimeter set to read 55 VDC to
check voltage on white/red wires at J2 connector
of EMM. V oltage at EMM conne ctor should b e
approximately 30 V.
