ezgo golf cart - rear wheels locked

[drummer4321]

Hi, I'm new here. I just bought my first golf carts yesterday. Ones a Columbia ParCar, which i will be posting about soon, and the other one is an EzGo Marathon(i think). The ezgo is the one i am starting with.
So, the problem i am having right now is that the back wheels don't spin. Any ideas what could be causing this?

Also does anyone have a wiring diagram, because there is a set of loose wires inside the dashboard panel.

I haven't had a chance to take any pictures yet, so attached are the ones the guy i bought it off of sent me.

Thank you in advance,
Mike
