Battery shut-off switch

I had the exact same problem with my new boat - cranking battery would go completely dead after two weeks and the only other items hooked up to it are my GPS and radio. Come to find out, it was the radio draining the battery. One perko switch later and everything is good to go.

Maybe the guy at the dealer was right about radio memory wire in boats. Don't drain a truck battery but will drain down a battery in a boat? Maybe cause usually drive a truck everyday and the boat when you get a chance.
