My son drives this car and he changed out his first battery. When he>bought the battery he didnВ’t notice that the positive post was on the>opposite side as the battery that was in there before that. You can>see where this is going. He continued to hook it up with the posts>backwards and after having what he thought to be the negative side>connected, he touched the postive connector to the negative post for a>breif second until the power distribuition box started smoking. IВ’m>not sure what exactly this incident did or normally does. We got the>right battery hooked in there and the car starts, but many interior>electronic­s donВ’t work. Also, the car sounds horrible. It seems to>be running at a much higher idol speed and the overall pitch is>higher. I put it into gear but was afraid to drive it out of the>driveway because the response was just not there. It feels like a>completely different car. So that is my issue and I was wondering>what anyone thought. I would like to fix this problem on my own>instead of paying the big bucks, but IВ’m not positive if simply>changing the blown fuses will fix the problem. Thanks for any>suggestions.
