Hi,The only things that can happen in this sort of scenario is either the connection to the battery did blow out some fuses/links and you just missed them, or specifically if the battery is reversed it can cause widespread electrical damage to most anything electronic in the vehicle (when polarity is reversed, the fuses are no protection as they are hit after the current is through everything).With major electricals down, it is nearly certain there are fuses/links that have been overlooked... go back through and verify all fuses/links manually... pull them out, resistance test etc. Something is blown out unless you got the battery in backward.
