TROUBLESHOOTING GUIDE
PROBLEM POSSIBLE CAUSE SOLUTION
Power ON indicator does
not light after being
plugged into AC for 30
seconds.
AC outlet is dead.
Plug in a lamp or other appliance to
check for voltage. If controlled by
a wall switch, be sure switch is on
and try to prevent accidental shut
off while charger is working.
ERROR indicator lights
RED solid.
Output lead connections
to battery may be
reversed.
Switch (reverse) connections at
battery.
Battery voltage
<3 volts.
Battery may be damaged and should
not be recharged. Allow battery to
“recover” by letting it “rest” without
a load.
Battery was just recently
removed from a load
(lights, electronic
equipment) or not
used for extended time
without a charger-
maintainer.
If battery is healthy and just deeply
discharged it should recover
its voltage (rise above 3 volts)
sufficiently to allow charger to begin
an attempt to fully recharge it.
Battery has “rested” and
still cannot be recovered
– recharged.
Battery should be safely discarded
– recycled.
ERROR Indicator lights
RED blinking.
Battery(s) may be weak,
heavily sulfated, or too
large to fully charge
before unit times out.
Allow battery to remain in
Maintenance-Float mode for 72 hours
or more and then attempt to recharge
again.
Battery may be so large
it may require a second
full recharge.
Reboot unit by unplugging from
A.C. electrical outlet, disconnect
from battery so there will be no
electrical power going to the unit
from either direction, wait 10
seconds, connect to battery first
then plug into A.C. outlet
Battery Condition
Indicator lights YELLOW
( Before battery has been
completely charged).
Battery can be weak
due to sulfation, self
discharge or was very
deeply discharged.
Attempt a full recharge and recheck
after completion. If still YELLOW,
follow next procedure (“After battery
has been completely charged.”)
