I have a 91 ezgo marathon that has started messing up when I installed new batteries. It will go real fast then drop off to nothing and not move. Has anyone had the same problem or does anyone have any suggestions. Please help we cant afford to go a new cart right now. Thanks to all who post.

Sounds like a low charge, bad battery or battery connection.
Make sure that the batteries are wired correctly, the cables are in good condition and the connections are clean and tight.
What is the total pack voltage measured at the charging receptacle? It should be 38.2v or better.

I am going to let it charge all night and see what happens. I have tested all the battries and they tested good. I will post the results. thanks

well took it out and it run fast for a few minutes. then when coming back up the road started running slow again and barely made it back. checked the batteries and had 38.9 volts on them. I'm at a loss now...
