FIGURE 3
CHARGING IF BATTERY IS INSTALLED IN A VEHICLE
a) Check polarity of battery posts - For top-mounted battery posts, the Positive post (marked POS, P, +) usually has a
larger diameter than the Negative battery post (marked NEG, N, -). For side-mounted battery terminals, the terminals
are marked Positive -red and Negative -black.
b) Attach charger clamps to battery connections, as follows, ensuring a good connection (if there is a mistake, the Reverse
Polarity Indicator will light):
NEGATIVE-GROUNDED VEHICLE: Connect the POSITIVE (RED) charger clamp to the POSITIVE (POS, P, +) battery post.
Then, connect the NEGATIVE (BLACK) charger clamp to the vehicle chassis, or the engine block (away from the battery).
Do not connect the clamp to the carburetor, fuel lines, or sheet-metal body parts: connect only to a heavy gauge metal
part of the frame or engine block.
NOTE:
The NEGATIVE-GROUNDED system is the most common in today's vehicles.
c) Set charger's Charge Rate 2/6/10A to appropriate setting according to battery size.
d) Plug battery charger power cord into grounded AC power outlet and refer to Appendix A at the end of this manual
for approximate charging times.
e) When charging is completed, disconnect cables and clamps in reverse order from which they were connected.
NOTE:
Use of Extension Cords
.
When using an extension cord, observe the following important safety information:
• Before using any extension cord, ensure that the wire size is at least 14 AWG for up to 100 feet and 12 AWG for
longer than 100 feet.
• Use only a good quality, good condition, UL-approved extension cord, and ALWAYS connect charger to the extension
cord first before plugging the extension cord into a 110/120VAC power outlet. The use of a poor quality extension
cord or one that is not in good repair could cause fire and/or electric shock.
• Use a three-wire extension cord with a 3-prong plug and 3-conductor socket.
