Get new batteries If your batteries are 2-3 years old its time for new ones. You can check the output of the charger by using a digital voltmeter Set the meter to 200 vdc and plug it into the two outter holes of the charger port with the charger plugged in you should read 27-30 volts. and with the charger unpluged you can aslo read the voltage of your batteries. fully charged they should read 25 -27 volts. If when charging you don't read 27-30 volts then the charger isn't working and you can get an offboard charger cheaper than the onboard just charge thru the charger port on the joystick. Hope this helps
