Default Re: What did I do and how do I fix it? 1953 Mercury

OK, put a better charger on for a couple of minutes, headlights came on. I disconnected charger and headlights dimmed then out so I think I'm on to something. Will pick a new battery today. I don't understand how connecting that wire that has been there for years would cause the battery to short out (?). Also, do battery chargers care if it's positive ground or not?
