Took the fzs out this weekend ran fine for about 15 mins then dies.....I saw that the battery had gone bad levels got to low I should have known then the charger was very warm when I pulled it off that morning. I changed the battery out but now it will not start the dash lights up but will not try to turn over. I did not look at it very long I just put it on the trailer and took the boat out that day. As I start to look it over to try and get her running again what all should I be looking for.
