ok thank you, i did check the wires going to the control card but i will check them again. As far as the battery, I just bought a new battery for it a year ago, so i'm hoping that's not the case but definitely good advice thank you. This last time it quit on me, they just pulled it off the charger and went maybe 10 feet and it quit on them with a full battery. I will start tracing wiring and seeing if i can find something. Thank you !
