Sears 200.71310 - Manual (Page 7)

AMMETER:
The ammeter indicates the measured amount of
amperes being drawn by the battery. When you first
start charging a battery, the reading will be high, with
the needle near 10 using the 10 amp charging rate.
• In the MANUAL setting, as the battery charges, the
needle will fall to about 4 or 5 amps, indicating a
charged battery.
• In both AUTOMATIC settings, the needle will fall to
zero and the charger will shut off when the charger’s
control circuit senses a full charge. A freshly charged
battery’s voltage will drop shortly after charging, and
the charger, if left connected, may resume charging.
This off-and-on cycling will continue until the battery's
voltage no longer drops enough to restart the charger.
• At the 2 amp charging rate you will notice very little
needle movement;
When cranking the engine while using the ENGINE
START feature, the needle will swing into the Start (red)
area of the scale.
LED INDICATOR:
The green LED INDICATOR will glow when the charger
senses that the battery has reached a full charge.
• When using the MANUAL charge rate, discontinue
charging when the LED glows and the AMMETER
needle is about 4 to 5 amps in the 10 Amp setting.
• For deep cycle batteries, you may wish to allow the
battery another one or two hours of charging
after the LED glows to obtain a maximum charge.
When using AUTOMATIC charge rates, the LED
will cycle on and off indicating the charger is main
taining the battery's state-of-charge.
Charging Your Battery
Charging a battery in the vehicle:
1. Arrange the power cord and charging leads carefully
to avoid damage that could be caused by the hood,
door, or moving engine parts.
2. Keep clear of fan blades, belts, pulleys, and other
parts that can cause injury.
3. Check the polarity of the battery posts as indicated
on the battery case: POSITIVE (POS, P, or +) and
NEGATIVE (NEG. N or -)• NOTE: The positive post
on top-post batteries is usually larger than the
negative post.
4. Identify which battery post is ground or connected to
the chassis. THE NEGATIVE POST IS
NORMALLY THE ONE THAT IS GROUNDED.
5. To charge a negative grounded post system:
Connect the red (POSITIVE) battery charger clamp
to the ungrounded POSITIVE (POS, P, -i-) post of
the battery. Then connect the black (NEGATIVE)
clamp to a heavy, unpainted metal part of the
chassis or engine block, away from the battery. Do
not connect clamp to carburetor, fuel lines, or sheet
metal parts.
