Make sure all batteries are to full level with distilled water. Careful not to overfill or will overflow when charging. Hook up charger and let it shut off. Leave it connected. Jump it off from another cart or mower or bike. (Not car) make sure you are hooked up in sequence. There is a first and last battery. Should kick back in charger and allow to fully charge. They have a “safety” if batteries get too low and won’t allow the charger to do its job. I had same issue on a club car.
Maybe? Hope it might do the trick.
