Please read through this table for a possible solution if a problem
occurs. |
|
PROBLEM |
POSSIBLE CAUSE |
SOLUTION/REASONS |
|
No ammeter
reading. |
Clamps not making
good connection. |
Check for poor
connection at battery. Make sure clamps and posts are clean. |
|
2-amp charge rate. |
Ammeter needle
will indicate little activity at the 2-amp charge rate. |
|
No AC power
reaching charger. |
Check AC outlet
and extension cords for loose fitting plug. |
|
Check for open
fuse or circuit breaker supplying AC outlet. |
|
Circuit breaker in
charger cycles on and off with a clicking sound. |
Shorted battery
clamps. |
Separate the
clamps. |
|
Circuit breaker
cycles when current draw is too high. |
|
Check for worn
cables and replace if needed. |
| |
|
Shorted battery. |
Have a Sears
Service Center test the battery. |
|
Charger leads
reversed on battery. |
Correct
connections. |
|
Ammeter reads less
than selected charge rate when charging. |
Extension cord too
long or gauge too small. |
Use shorter or
heavier extension cord. |
|
Battery has weak
cell or sulfated plate. |
Sulfated battery
will eventually take a normal charge if left connected. If the
battery will not take a charge, have it tested by a Sears Service
Center. |
|
Battery is
partially charged. |
Continue charging
battery. |
|
Charger makes a
loud buzz or hum. |
Transformer
laminations vibrate (buzz). |
Continue charging.
Buzz is not abnormal. |
|
Shorted diode
(hum). |
Have charger
tested by a Sears Service Center. |
|
Short start cycle
when cranking engine. |
Drawing more than
50 amps for a period equal to or less than 10 seconds. |
Crank time varies
with the amount of current drawn from the charger. If cranking draws
more than 50 amps, crank time may be less than 10 seconds. |
|
Failure to wait
for 4 minutes (240 seconds) between cranks. |
Wait 4 minutes
before next crank. |
