AC ELECTRICAL CONNECTIONS
PLUGGING CHARGER IN
Your charger requires a 120 V AC electrical wall outlet receptacle installed according to local codes and
ordinances.
USING AN EXTENSION CORD
MINIMUM RECOMMENDED EXTENSION CORD
An extension cord should not be used unless absolutely necessary. Use of an improper extension cord
could result in a risk of fire and electric shock. If an extension cord must be used, make sure:
Locate charger as far away from battery as DC cables pemit.
Never place charger directly above battery being charged; gases from battery will corrode and
damage charger.
Never allow battery acid to drip on charger when reading electrolyte specific gravity or filling battery.
Do not operate charger in a closed-in area or restrict ventiation in any way.
Do not set a battery on top of charger.
DC CONNECTION PRECAUTIONS
Connect and disconnect DC output clips only after removing AC cord from electric outlet.
Never allow clips to touch each other.
Attach clips to battery and chassis as indicated in the Connecting Your Battery section.
Position AC and DC cords to reduce risk of damage by hood, door or moving engine part.
Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has a larger diameter than
NEGATIVE (NEG, N, -) post.
Determine which post of battery is grounded (connected) to the chassis.
If negative post is grounded to chassis (as in most vehicles), see step “ For negative-grounded
vehicle”. If positive post is grounded to the chassis, see step “For positive-grounded vehicle”.
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-gauge metal part of the frame or engine block.
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-gauge metal part of the frame or engine block.
When disconnecting charger, turn switches to off, disconnect AC cord, remove clip from vehicle
chassis, and then remove clip from battery terminal.
The pins on plug of extension cord are the same number, size, and shape as those of plug on charger.
The extension cord is properly wired and in good electrical condition.
The wire size is large enough for AC ampere rating of charger as specified in the chart below:
PREPARING TO CHARGE
If it is necessary to remove battery from vehicle to charge, always remove grounded terminal from
battery first. Make sure all accessories in the vehicle are off so as not to cause an arc.
Be sure area around battery is well ventilated while battery is being charged.
Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. Do
not overfill. For a battery without removable cell caps, such as valve-regulated lead-acid batteries,
carefully follow manufacturer's reacharging instructions.
Study all battery manufacturer's specific precautions while charging and follow recommended rates of
Determine voltage of battery by referring to car owner’s manual and make sure that output voltage
selector switch is set at correct voltage. If charger has adjustable charge rate, charge battery initially
at lowest rate.
