OPERATION
When using the ENGINE START
feature, the needle will swing into the

Start (red)

area of the scale while you
are cranking the engine.
The percent of charge scale is intended
as a visual aid to help simplify reading
the state of charge of the battery. The
meter is scaled for use with the 10 amp
charge rate only. For the 2 amp charge
rate use the red triangle. The percent of
charge is based on current drawn by the
battery. For this reason accuracy will
vary with the size and battery type.
Charging Your BatteryCharging a battery in thevehicle:
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. (Fig. A)
5. To charge a negative grounded post
system:
Connect the red (POSITIVE) battery
charger clamp to the ungrounded
POSITIVE (POS, P, +) 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. Donot connect clamp to
carburetor, fuel lines,or sheetmetal parts.
To charge a positive grounded post
system:
Connect the black (NEGATIVE) battery
charger clamp to the NEGATIVE (NEG, N, -)
ungrounded post of the battery.
Then connect the red (POSITIVE) clamp
to a heavy, unpainted metal part
of the chassis or engine block. Do not Continued...
NEGATIVE GROUNDED SYSTEM
Figure A
connect clamp to carburetor, fuel lines,
or sheet metal parts. IMPORTANT: Wear
safety glasses and face away from
the battery while making connections.
6. Connect the clamp to the battery
post and twist or rock back and forth to
make a solid connection. This will help keep
the clamps from slipping off the posts and
causing sparks.
7. Select the charge rate with the
Selector Switch then plug the power cord
into a grounded AC outlet to begin
charging.
8. The charger will not stop when the
battery is fully charged. For this reason
it is important to check charging
progress frequently. Overcharging
can damage a battery, you must moni-
tor and unplug charger when battery is fully
charged.
9. When the battery is fully charged,
the AMMETER pointer will fall to about
half the charge rate selected. For specific
positions, refer to the “Ammeter” section
in “Using your battery charger” on page 6.
10. When the battery is fully charged,
unplug the charger power cord before
attempting to disconnect charger clamps.
11. Standing away f rom the battery, re-
move the charger clamps in this order:
(1) from the chassis connection and,
(2) from the battery post or terminal.
12. Clean and store the battery charger
in a dry location.
