1965 dart 270 convertible no electrical power

the battery cables on my dart are set up as black for positive and red for negative. i just got the car and it had a dead battery. i went to hook up the charger and quickly realized that i was going by cable color not terminal markings. as i started to toich the negative terminal i got a spark before i made the connection. prior to my screw-up the car would turn over and start. now i have nothing, it won't turn over and the lights won't come on. does anyone know which fuse i blew up and where it is located? the car is a 65 dart.
