15. DC CONNECTION PRECAUTIONS
a) Connect and disconnect dc output terminals only after removing ac cord from electric outlet. Never allow output terminals to touch
each other.
b) Attach output terminals to battery and chassis as indicated in 16(e), 16(f), and 17(b).
16. FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK NEAR BATTERY MAY CAUSE BATTERY
EXPLOSION. TO REDUCE RISK OF A SPARK NEAR BATTERY:
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 a larger diameter than NEGATIVE
(NEG, N, -) post.
d) Determine which post of battery is grounded
(connected) to the chasis. If negative post is grounded to
chasis (as in most vehicles), see (e). If positive post is
grounded to the chasis, see (f).
e) For negative-grounded vehicle, connect POSITIVE
(RED) output terminal from battery charger to POSITIVE
(POS, P, +) ungrounded post of battery. Connect NEGATIVE
(BLACK) output terminal to vehicle chassis or engine block
away from battery. Do not connect output terminal to
carburetor, fuel lines, or sheet-metal body parts. Connect to
a heavy gage metal part of the frame or engine block.
(Refer to Figure 1).
f) For positive-grounded vehicle, connect NEGATIVE (BLACK)
output terminal from battery charger to NEGATIVE (NEG, N, -)
ungrounded post of battery. Connect POSITIVE (RED) output
terminal to vehicle chassis or engine block away from battery.
Do not connect output terminal to carburetor, fuel lines, or
sheet-metal body parts. Connect to a heavy gage metal part of
the frame or engine block. (Refer to Figure 2).
g) When disconnecting charger, disconnect AC cord, remove
output terminal from vehicle chassis, and then remove output
terminal from battery terminal.
h) See operating instructions for length of charge information.
