      the cart came with a powerdrive charger and it will not turn off even after 16 hours+. i have a powerdrive 2 charger that i plugged in and it turns on after abour 3-5 seconds and then off then back on and stays on (OBC charger on/off control works). the PD2 was off after i got home but i don't know how long it took to finish charge or if it stopped after 16 hours. The pack voltage was at 51.1vdc. Also, i load tested batteries and they are all good and less than 6 months old by date code. i have also tried to reset the OBC. The powerdrive and powerdrive 2 are basically the same right? OBC controls charger.

          for this problem I would unplug the two prong plug at the mcor install a jumper and drive it see if it drops out, also on the early carts they do not have the diode in the run tow switch circuit this can also cause drop out.

            basically yes they use different transformers and different diode packs, so you're most likely have one of two problems the relay is stuck on, or one diode is open not giving your pack full voltage and the OBC does not shut off. on my site under parts the relays are about $4.00.

              one more thing to try the gray wire from the charge receptacle unplugs at the OBC, un plug the gray wire and if the powerdrive charger comes on you know the relay is stuck on.
