2001 Club Car Charger Won't kick off

[betarho]

I have a 2001 Club. The batteries are new and were fully charged at dealer. The OBC is new along with the receptacle. When I first tried to charge the batteries the Powerdrive charger would shoot up to 20 amps and run for about 3 minutes and kick the breaker. I got another charger from a friend and the this did not occur. After two hours I hooked my charger back up and the breaker didn't kick. A full charge was completed with my charger as the breaker didn't kick at lower amps. I changed the breaker and hooked up the charger. It kicked on to 10 amps and shut off and then back to 10 amps charging. This was after the cart ran 18 holes. Ths was 3 pm. I returned at 9:30 am the next morning and the charger was still running but at 0 amps. This happened again the next day. I don't think the batteries are bad or the other charger wouldn't have worked. Any suggestions? Maybe the timer in the charger. All the batteries tested good at the dealer two weeks ago.
