of battery charger. Charge battery initially at lowest
charge rate, if possible.
12. CHARGER LOCATION
a. Locate charger as far away from battery as dc cables
permit.
b. Never place charger directly above battery being
charged; gases from battery will corrode and damage
charger.
c. Never allow battery acid to drip on charger when reading
electrolyte specific gravity or filling battery.
d. Do not operate charger in a closed-in area or restrict
ventilation in any way.
e. Do not set a battery on top of charger.
13. DC CONNECTION PRECAUTIONS
a. Connect and disconnect dc output terminals only after
setting any charger switches/controls to OFF position
and removing AC input connection.
DANGER—NEVER allow positive/negative connections
to touch each other.
b. Attach connections to battery and DC neg(-) bus as
indicated in 14(e), 14(f), and 15(b) through 15(d) below.
14. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN
VESSEL. A SPARK NEAR BATTERY MAY CAUSE BATTERY
EXPLOSION. TO REDUCE RISK OF A SPARK NEAR
BATTERY:
975-1038-01-01
a. Position ac and dc cords to reduce risk of damage by
hood, door, or moving engine part.
b. Stay clear of fan blades, belts, pulleys, and other parts
that can cause injury to persons.
c. Check polarity of battery posts. POSITIVE (POS, P, +)
battery post usually has larger diameter than NEGATIVE
(NEG, N,–) post.
CAUTION—The Negative (-) terminal of this battery
charger is grounded.
d. Determine which post of battery is grounded (connected)
to the DC neg(-) bus. If negative post is grounded to DC
neg(-) bus (as in most vessels). This battery charger is
not designed for a battery positive referenced ground
(DC neg(-) bus connection) system, only use in a
Negative grounded vessel system.
e. For negative-grounded vessel, connect POSITIVE (RED)
connection from battery charger to POSITIVE (POS, P, +)
ungrounded post of battery. Connect NEGATIVE
(BLACK) clip to vessel DC neg(-) bus or engine block
away from battery. Do not connect clip to carburetor, fuel
lines, or sheet-metal body parts. Connect to a heavy
gage metal part of the frame or engine block.
f. See operating instructions for length of charge
information.
g. When disconnecting charger, turn switches to off,
disconnect AC input power, remove connection from
vessel DC neg(-) bus, and then remove connection from
battery positive terminal.
