Well,that is the part I'm not sure of. I charged it yesterday and it only took it about 2 hrs to reach full charge (according to the battery charger) with a voltage reading of 12. 4. I rode it a bit with several starts and stops and it did fine. I removed the cables and cleaned and traced them checking for good clean, thight connections.The problem seems to crop up when it sits several days without any use. I suspect it may have the origional battery as it is a 2005 cart and the battery is an Ezgo battery with a sticker that says D5 on it.How do I check to see if it is charging?
