Third battery

Third battery
I have two engines, and two battery switches. I just installed two stereo amps in my cabin today. I ran two 6 gauge wires from battery #1 in the bilge to the third battery i installed in the cabin closet. i would like the third battery to get charged from the alternator, but I dont want it to draw from battery #1. Now what?? Isolator?

all you need is a 250 watt diode in the wire that ties the third battery into the other two. then the current will only flow in one direction. 5 bucks at radio shack or 10 bucks at any electronics store.
