Charging Your Battery
Charging your battery in the vehicle:
1. Arrange the power cord and charging leads care-
fully in order to avoid damage that could be caused
bythe hood, door, or moving engine parts.
2. Keep clear ofthe fan blades, belts, pulleys, and
other parts that can cause injury.
3. Check the polarity ofthe battery posts using the
identification marks on the battery case: POSITIVE
(POS, P, +) and NEGATIVE (NEG, N, -).
4. Identify which battery post isgrounded or con-
nected to the chassis. THE NEGATIVE POST IS
NORMALLY THE ONE THAT IS GROUNDED.
5. To charge s negative grounded post system:
Connect the red (POSITIVE) charger clamp to the
ungrounded POSITIVE (POS, P, +) post of the
battery. Next, connect the black (NEGATIVE) clamp
to an unpainted, heavy metal part ofthe chassis or
engine block, away from the battery. Do not
connect clamp to carburetor, fuel lines, or sheet
metal parts.
To charge a positive grounded post system:
Connect the black (NEGATIVE) charger clamp to
the ungrounded NEGATIVE (NEG, N, -) post ofthe
battery. Then connect the red (POSITIVE) clamp to
an unpainted, heavy metal part of the chassis or
engine block, away from the battery. Do not
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 offthe
posts and causing sparks.
7. Set the VOLT/AMP SELECTOR switch and timer
switch to the OFF position. Next plug the power
cord into a grounded AC outlet.
8. Set the VOLT/AMP SELECTOR switch to the
desired charge time, from 30 to 135 minutes. If
more than 135 minutes of charging time is needed,
the HOLD position can be used. When using the
HOLD feature, the battery being charged must be
monitored closely to avoid over charging.
9. Set the TIMER to the desired charge rate. (See
"Setting the Controls" on pages 7 and 8, and
"Calculating Charge Time" on page 11 .)
10. When the battery isfully charged in the MANUAL
mode, the AMMETER pointer will fall to about half
the selected charge rate. The BATTERY TEST will
be in the green area ofthe meter. Forspecific
positions, see the "Setting the Controls" section on
pages 7 and 8.
