the battery.
Ammeter Readings
The ammeter shows how much
charging current is drawn from the
charger (to the battery). When a dead
or low battery is charged the charger’s
ammeter will register at the high end. As
the battery charges, the reading will move
down toward the low end, resting on zero,
when the battery is fully charged. When
using the battery in engine starting mode
(discussed further down this page) the
needle on the ammeter will peg toward the
high end of the ammeter.
Do not depend on reading the
ammeter to approximate how long
charging will take. Even at full charge the
ammeter will still be providing as much as
50 percent of the charger’s output rating.
It’s best to monitor the battery’s charge.
Sometimes, certain conditions such as a
cold battery, a sulfated battery, or a deeply
discharged Lead Calcium battery (on
many newer cars) may cause the ammeter
to read near a full charge, when the
charging process is only beginning.
Note: Cold batteries (at or below 32°
Fahrenheit) begin charging at a low
rate and then increase as the battery
warms. When the battery charges
up, the rate will decrease at a normal
rate. Do not charge a frozen battery.
SHORTED BATTERIES will read on the
ammeter as a high end peg at the begin-
ning of the charging process. If after 5-10
minutes the needle does not move off of the
high end, the battery probably has a short
circuit. Unplug the charger and discontinue
use. Have the battery checked by a quali-
ed technician.
Engine Starting
Note: This charger’s high-current output
can help start vehicles with weak
batteries. Some newer vehicles
with onboard computers may
be damaged from this process.
Thoroughly read the vehicle owner’s
manual before using this procedure.
Connect the charger to the battery 1.
as discussed on pages 7 and 8, but
leave the battery cables attached.
Set the charger to charge the battery 2.
for 5-10 minutes according to the
appropriate charge rate for the size
of the battery as explained on the
previous 2 pages.
Set the select function switch to 3. Start
and the select switch to 55A.
(See FIGURE 1 on page 6.)
Try to start the vehicle. If it doesn’t 4.
start in 12 seconds, stop and allow
the charger to rest for 4 minutes.
After resting, it may be benecial to
charge the battery as explained in
step 2 before attempting Repeat this
process until successful.
Note: If the engine continues to spin
but will not start after several
tries, than you may have another
problem unrelated to charging.
Stop attempting to start/charge the
battery until the problem is found
and corrected. Continued engine
cranking may damage the vehicle’s
starter.
