NOCO - Error LED Indications On GEN - Support

Error LED Is Illuminated or Flashing

Understanding GEN LEDs

Each battery bank contains two (2) LEDs - a CHARGE LED and an ERROR LED. The CHARGE LED indicates the charging process (Red when charging, Green when charged) and the ERROR LED displays a Reverse Polarity or Error Condition. 

Error

        Reason/Solution

Orange LED

If a Reverse Polarity condition exists, the ORANGE ERROR LED will illuminate. This ERROR condition will be displayed whether the charger is plugged in or disconnected from an AC power source. Reverse the battery connections to fix this ERROR.

Flashing Error LED

If an ERROR condition exists, the Charge LED(s) will flash, and/or the ERROR LED with illuminate and/or flash. There are several reasons an ERROR condition could exist. For help troubleshooting ERROR conditions, see the section titled Troubleshooting below.

 (See Graphic Below)

 

Troubleshooting When Flashing LEDs Illuminate

Possible Problem

        Reason/Solution

Battery Voltage   Incompatibility        

Check to make sure you have a 12V battery. This battery charger is for 12V batteries only. If you attempting to charge a battery that is other than 12V, it could cause this ERROR condition. Charge the appropriate battery to resolve this ERROR condition.

Low Voltage Battery

If the battery voltage is below 2.0VDC (12V), it could cause this ERROR condition. In this situation, the battery charger has determined that the battery voltage is too low to begin a normal charge cycle. To increase the battery voltage and allow the battery charger to begin charging, you will need to jump start the battery

Abnormality Protection

This ERROR condition is the result of the battery charger being in the Bulk mode for more than eighty (80) hours. This ERROR condition is the result of a bad battery. To resolve this ERROR condition, take the battery to a local battery store for an evaluation.

Blown Fuse In Battery Connector Harness

Check the fuse in the battery connector harness. If the fuse in the battery connector harness has blown, it could cause this ERROR condition. Replace the fuse with a 15A Automotive Blade Fuse to resolve this ERROR condition.

Corrosion On Battery Terminals

Check the battery connections for battery corrosion. If battery corrosion is present on the battery connections, it could cause this ERROR condition. Remove the battery corrosion to resolve this ERROR condition.

Loose Battery Connections

Check the battery connections to the battery. If the battery connections are loose, it could cause this ERROR condition. Tighten the battery connections to resolve this ERROR condition.

Sulfated, Damaged, Or Weak Battery 

If you have checked all other possible ERROR conditions and cannot clear the ERROR, it is probably the result of a sulfated, damaged, or weak battery. To properly diagnose a sulfated, damaged, or weak battery, take the battery to a local battery store for an evaluation. The battery store will advise if the battery can be charged or needs replaced.

When No Lights Come On While The Battery Charger Is Plugged Into An Electrical Outlet.

Possible Problem

        Reason/Solution

Weak AC Connection       

Check if the AC outlet has power. If the AC outlet has no or limited power, it could cause this condition. Plug a light into the AC outlet to check if the outlet has power. If the light is extremely dim, this could be the result of limited AC power. The battery charger is designed for use at 70-130VAC. If there is no power or the power is below 70VAC, locate another AC outlet that has sufficient power to resolve this ERROR condition.

Bulk Timeout

For safety, if the charger is in bulk mode for 41hours it will automatically stop charging and all LEDs will flash. If this happens, have the battery tested as it might be defective. To restart charging, disconnect AC Power and then reconnect.
