¾ NEITHER THE RED OR GREEN LIGHT TURN ON (Both models) – This
is an abnormal condition and most likely indicates that the charger is not
properly connected to the AC power.
¾ RED LIGHT FLASHING (All models except 6V Junior) – The red light
flashing indicates that the battery charger has AC power available and that
the microprocessor is functioning properly. If the red light continues to
flash, then either the battery voltage is too low (less than 3 volts) or the
output alligator clips or accessory ring terminals are not connected
correctly.
¾ RED LIGHT ON STEADY (Both models) – Whenever the red light is on
steady, a battery is connected properly and the charger is charging the
battery. The red light will remain on until the charger completes the
charging stage.
¾ GREEN LIGHT FLASHING (1.25A only) - When the green light is
flashing, and the red light is on, the battery is greater than 80% charged
and may be removed from the charger and used if necessary. Whenever
possible, leave the battery on charge until the green light is solid.
¾ GREEN LIGHT ON STEADY (Both models) - When the green light stops
flashing and burns steady, the charge is complete and the battery can be
returned to service if necessary.
¾ ALTERNATING RED & GREEN LIGHTS FLASHING (PLUS) This is
abnormal and most likely indicates either that the battery is sulfated or that
there is a poor electrical connection between the charger DC output and
the battery posts.
TROUBLESHOOTING CHECK LIST:
1. NEITHER OF THE CHARGER LIGHTS TURN ON AFTER THE AC POWER
PLUG IS CONNECTED TO THE AC ELECTRICAL OUTLET:
For the 1.25A
model: Check the charger AC power plug connection at the AC electrical outlet.
Verify that the AC electrical outlet is functioning properly by plugging in another
appliance or a voltmeter. For the 0.75 A model, also make sure that the charger output
is properly connected to the battery.
2. THE CHARGER GREEN LIGHT GOES ON IMMEDIATELY WHEN AC
POWER IS APPLIED TO THE CHARGER:
The charger connections at the
battery may be intermittent, the battery may be defective, or the battery might already
be fully charged.
3. CHARGER IS CHARGING BUT THE GREEN LIGHT DOES NOT TURN ON
IN A REASONABLE AMOUNT OF TIME:
The battery may be large and requires
more time to fully charge than originally expected, there may be another appliance
drawing electric power from the battery while it is charging, or the battery may be
defective. Also, a newly purchased battery may not be fully charged and may take
longer to charge initially.
4. THE RED LIGHT COMES ON AGAIN AFTER THE GREEN LIGHT CAME
ON.
There may be another appliance drawing electric power from the battery causing
its voltage to drop below the reset level. The battery charger then goes back into full
charge mode. Also, the charger connections at the battery may be intermittent or the
battery may be defective.
