little power no speed 36v

[ol cart]

Hello, hoping to get help with my 36v ezgo resistor cart 1984 model. ok ,,the other evening driving along it just quit.turns out a battery terminal melted off.. got new battery for it, charged overnight, the auto charger shut off as it supposed to, now its like I have no power barely pulls itself with it floored. oddly it seems normal when in reverse...I fixed a loose battery cable terminal, cleaned every cable..all wires are fine now, within the past year I have already replaced the solenoid, throttle control and sweep... it was running just fine until the cable melted, I know this happens it they get loose they get hot, but I am at a loss at the problem now????? could it have damaged the electric motor? any help would be great. thank you. Kevin.

To get started troubleshooting you are going to need to make some voltage measurements on the battery bank, especially across the battery you replaced. Others here can help you better than myself. I would guess the motor may be ok.
