The problems with miswiring the batteries are many and I don't think that can be resolved here. Some hands on testing is going to be needed. I would call a mobile tech over to assist you in this. Nevertheless, I will opt out of this question so another tech might offer something if they feel they can be helpful here.
I hate not to be able to resolve a question, but these are usually just too complex to do in this format..........sorry I wasn't able to help out here.
