Charging Problem

[basstracker1959]

I have a 1992 Ezgo 36 volt electric cart, I have 5-8 volt batteries in my cart(I was told this would work on 36 volt carts) and it has. My problem is my Textron total charge III charger keeps cutting off a few seconds after plugging in to cart. I keep trying it and sometimes it will charge for a hour or so then cut off again, on rare occasions it will stay on for a full charge. I have put new receptacles on charger and cart. The batteries are 1 year old, also all new cables on batteries and cart runs fine. Could the problem be in the charger? What might be the problem?
