Kinda sounds like a failed OBC.

The relay in the charger can stick closed but that’s usually easy to check. First, there should be a delay from plugging the charger in until it actually turns on. Usually 5-10 seconds. The “click” when the charger turns on is the relay clicking on.
If the relay is stuck in the On position the transformer in the charger has AC power all the time. Plug the charger into the AC wall outlet, but Not to the cart. The charger should make No noise. If you can hear the transformer hum, the relay is stuck on.

Another way is with the charger plugged into the cart and charging, pull apart the yellow fuse holder on the grey wire on the back of the charge receptacle. The charger should turn off. If it does Not turn off, the relay is stuck.
If the charger passes those two tests your problem is the OBC.
