Hello I new at this but I need some help I have 2002 rancher 350es and I think I Fried my ecm cause it's hot to the touch and it won't shift or charge. Before this happen I called myself cleaning the connector by putting grease and soon as I did that I place the battery cables on and a big spark on the positive side and I check the fuses and a 30amp motor fuse and replace it but it didn't fix it and hasn't blown the new so could it be the ecm I really need help thanks
