battery light comes on and off

[donnell68]

i hit a huge bump during our long A$$$$ winter here in NY, afterwards my batter light keeps coming on and off, i bought it to the dealer and pep boys and nobody can tell me why it does that, they tried new battery, new connectors but i think when i hit that bump it made a wire loose somewhere. hereeeeee
also did anyone experience antifreeze in their engine i had to get a whoel ne engin because i got a crack in my engine
