Got an automatic EZGO battery charger that I'm trying to hook up to a Cushman GC400. I wired the crows foot plug onto the charger, and the wires on the recepticle are going straight to the + and - posts on the battery (like they do on an EZGO). When I plug the charger in, it begins to charge, and the meter jumps up to where it should for discharged batteries (20-25 amps), but I noticed that the cart didn't have a full charge when the charger shuts off. So after using it again I plugged the charger in, and when I went back in about an hour to check it, it had cut itself off. I unplugged, then replugged it in, and the meter jumped back up to 20-25, but again, after an hour or so I went back and the charger was off again. I've stood there for 15 min or so and it stays on. Plug is making good contact/ not overheating. Any ideas?
