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 maintenance-
charger is working.

(See page 10, item
2A
)
Output lead connections
to the battery set may be
reversed.
Switch (reverse) connections at the battery
set.
Battery set's voltage
<12 volts.
Battery set may be damaged and should not
be recharged. Allow battery set to “recover”
by letting it “
REST
” without a load.
Battery set was just recently
removed from a load (lights,
electronic equipment) or
used for extended time
without a maintenance-
charger.
If battery set is healthy and just deeply
discharged it should recover its voltage
(rise above 12 volts) sufficiently to allow
maintenance-charger to begin an attempt
to fully recharge it.
Battery set has “
RESTED
”
and still cannot be recovered
– recharged.
Battery set should be safely discarded –
recycled.
Battery Set Weak
Indicator lights
RED
blinking
.
Battery set may be weak,
heavily sulfated, or too large
to fully charge before unit
times out.
Battery set may be so large
it may require a second full
recharge.
Reboot unit by unplugging from AC
electrical outlet, disconnect from battery
set so there will be no electrical power
going to the unit from either direction,
wait a minimum of 30 seconds, connect to
battery set first then plug into AC outlet
Battery set Weak
Indicator lights
YELLOW
(
Before
battery set
has been completely
charged).
Battery set 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 set has been
completely charged.”)
Battery set Condition
Indicator lights
YELLOW
(
After
battery set
has been completely
charged).
Battery set still has an
unacceptable level of
sulfation.
Reboot unit by unplugging from AC
electrical outlet, disconnect from battery
set so there will be no electrical power
going to the unit from either direction,
wait a minimum of 30 seconds, connect to
battery set first then plug into AC outlet
Rested:
A battery set that has been as fully charged as possible and left disconnected
from maintenance-charger or any type load overnight.
