Ezgo charger problem now a cart problem

[Cookieman987]

So Ive been restoring a 2004 ezgo36v , and I'm an armature I admit, I wired my new charging recepcate backwards and blew the fuse on my power wise charger. So I replaced the fuse an it only put out like 2 amps. Did some research, countunity test checked connections and found nothing seriously wrong , so I bought a replacent capacitor from ez go (exact match) and put it in tonight ( positive I did not wire this one backward if u can even do that), plug it and charger came on and put out about 10 amps. So I watched it for a minute or so and the next thing. Ya know it starts SMOKIN and there's a FIRE in my battery compartment (insulation on the charging cable melted and burned in half). After I put the fire out and looked over everything I tried to turn the cart on and put it in gear and it will not even engage or go any where. Not shure what happened but hope Yall can help thanks
