TROUBLESHOOTING:
Symptom Cause Corrective Action
No voltage reading on meter
when connected to battery, and
the LED flashes red/green.
Connected reverse to battery,
or not connected to battery.
Break in DC cord, or
connector.
Battery too dead to charge. Correct polarity, or connect to
battery. On chargers having a
white and black wire, white is
positive.
Have a qualified person make
repair.
Replace.
When switched on, the red LED
does not light, and no amps read
on meter The panel mount fuse is
blown.
There is no AC power present
at the plug. Replace with one having the same
rating.
Check that there is power at the
source. If using an extension cord,
check that it is not damaged.
When I put a volt meter across
the output of the charger there is
no power coming out when I
switch it on. The charger must be
connected to a battery to turn
on.
The batteries don’t receive a full
charge. On wet cells, the
specific gravity will not rise to a
full reading after the charge has
completed.
The charger is too small for
the battery.
The charge profile is not set
correctly.
The cycle needs more time.
The battery is defective.
Check that the charger’s output is
about 10% of the amp hour rating
of the battery.
Recheck the dip switch setting. If
in doubt, contact us.
If you have a 4 position switch,
switch #1 position ON.
Replace.
The battery voltage reads well
below the rating of the battery,
and when powered up the LED
is red with a yellow flash, and
the amps are less than 5. The battery is very low, and
the charger is in a slow charge
phase until the voltage rises to
a safe level before full turn on. Leave connected, it may take
hours, but if the voltage rises even
a little bit, it should recover, and
turn the charger full on. (
Do not
allow your batteries to deep
discharge, it is the number one
cause of premature battery
failure
.)
When switched on, the LED
flashes red/yellow, and there is
no amp output on the meter Charger and battery voltage
mismatch Connect the charger to a battery(s)
with the same voltage rating.
The charger blows it’s fuse, or
branch circuit fuse/circuit
breaker as soon as it’s switched
on.
Charger is shorted Contact factory.
