  • I have plugged the AC cord to a power outlet, but why is the power LED is not on?
    Check for short circuit at DC outputs. Check for battery wiring connections. Replace blown fuses if necessary.
  • Why is the overheat LED displaying solid yellow?
    It indicates the ambient temperature exceeds range. Remove any obstructed objects blocking airflow around the charger. Wait for the charger to cool down, and then it will turn itself on again after the temperature drops.
  • Why is the over-voltage LED displaying blinking yellow?
    Battery voltage exceeds range. Please refer to user manual. Check, and correct DC wiring connections, wait for 30 seconds before plugging in AC power again. If the over-voltage LED continues to display blinking yellow even with correct DC wiring connections, unplug the chrager's AC power input and stop using the charger to avoid possible damages to the batteries or the connected electronic devices.
  • Why is the conneciton check LED displaying blinking yellow?
    One or more DC outputs are not properly connected to a battery terminal. Make sure none of the output cables are left unconneted. If all the output cables are connected to batteires, check for blown fuses inside each output cable. Replace damaged fuses with matching spare ones. Check on the polarity of DC wiring connections, and correct connections with matching polarity if necessary.
  • Why is the battery check LED displaying solid yellow?
    The charger remains in the bulk stage charging for more than 15 hours. There are a few possible causes.
       1. Onboard electronic devices continously draw charge from the battery.
       2. Battery system's capacity exceeds the charger's recommeded capcity (in Ah).
       3. User tries to charge a dead battery.
       4. Battery has one or more defective cells.
    If user is intentionally trying to charge a dead battery or a larger-than-recommended battery system, unplug AC power, wait for 10 seconds, and then plug in AC power again to restart a new charge cycle. Otherwise, run battery test and replace battery if defective.
