When the power is turned off and I plug the charger in the light will come on and then turn off seconds later. Although, when I have it powered on and put the charger in it will stay on for hours. Any clue why or what I can do to fix? I’ve replaced the battery and cleaned the battery connectors. I haven’t bought a new charger as I didn’t think it was the issue since it will give a charge, it hasn’t given out yet
