TROUBLESHOOTING

TROUBLESHOOTING
NO INDICATOR LIGHTS - If the indicator lights are both dark when power is applied and the charger is properly
attached to a battery, check to see if the receptacle is controlled by a light switch or power strip switch.
CHARGER STARTS UP IN READY MODE - If the charger READY light comes on when you first attach the battery (or in
less than 13 hours) then the battery is probably more than 14.4 volts (12 cells). The charger resets into float mode when
it detects a voltage over 21 volts. It will reach this voltage charging batteries over 15.6 volts (13 cells).
CHARGER WILL NOT SWITCH INTO FLOAT MODE - If the charger will not switch into the float mode, after 15 hours,
check to see if there was a power interruption. A power outage or glitch may have reset the charger timer for another 13
to 15 hour charge cycle.
CHARGE LIGHT ON WITHOUT A BATTERY - This indicates that the output cable or connector is shorted. If the light
goes out with the output cable removed then you should replace the cable. Do not attempt to charge a battery with a
shorted output cable.
RATTLE - If you think you hear a rattle inside the charger it is probably only a loose terminal strip screw. Once the output
cable is attached the rattle should go away.
