started the 350 sbc today and it started fine. went to store and wouldnt start. dead. starter was replaced about 1 month ago and battery is about 6 months old. when u turn the key the soliniod clicks so starter getting power and i checked the starter wires out and they look fine. i went to jump it and it fired right up after 2 sec of charge. went home turned off and immediatly tried to start agian, dead. tried the cables once again and fired up after a few sec of charge. im guessing alternator not charging the battery?
