c) Check polarity of battery posts.POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE (NEG, N,–) post.
d) Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis (as in most vehicles),
see (e). If positive post is grounded to the chassis,see (f).
e) For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, + ) ungrounded post of battery.
Connect NEGATIVE (BLACK) clip to vehicle chassis 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) For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from battery charger to NEGATIVE (NEG. N , -) ungrounded post of battery.
Connect POSITIVE (RED) clip to vehicle chassis 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.
g) When disconnecting charger, turn switches to off, disconnect AC cord,remove clip from vehicle chassis,and then remove clip from battery
terminal.
h) See operating instructions for length of charge information.
16. FOLLOW THESE STEPS WHEN BATTERY IS OUTSIDE VEHICLE. A SPARK NEAR THE BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE
RISK OF A SPARK NEAR BATTERY :
a) Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than NEGATIVE (NEG,N, -) post.
b) This battery charger has an automatic safety feature that will prevent it from operating if the battery
has been inversely connected. The charger does not allow charge current unless a voltage of at least
4V is sensed.
c) Connect POSITIVE (RED) charger clip to POSITIVE (POS, P, +) post of battery.
d) Position yourself and free end of cable as far away from battery as possible - then connect NEGATIVE (BLACK) charger clip to free of cable.
e) Do not face battery when making final connection.
f) When disconnecting charger, always do so in reverse sequence of connecting procedure & break first connection while as far away from
battery as practical.
g) A marine (boat) battery must be removed & charged on shore. To charge it on board requires equipment specially designed for marine use.
