All the lights on my charger are flashingUpdated 3 months ago

Please work through the following troubleshooting steps:

- Check the blade fuses on the 12V side of the charger to see if they're intact. If they have blown or melted, replace the fuses.

- Check the connections between the charger and the battery to ensure they are secure. 

- Try connecting this unit to another lithium battery to see if this issue persists.

- Try charging this battery with another charging source to confirm that the battery can accept charge.
