Electrical

Hit a bump on the road and ac, radio and gas pedal and dash lights all went crazy. Gas pedal wouldn't make car go even though it was on and in drive. Made it to AutoZone they tested battery, alternator and transmission they said all seems fine maybe clean corrosion on battery. We did, it worked for about ten minutes then it started doing it again. Not sure what to try next. Now it won't turn on, radio and stuff works but it won't turn over to start all the way.
