    Battery Isolator vs Seperator

    One of my batterys is used for starting, other has all the auxillary stuff hooked up to it. When theres a small current draw when the car is turned off, it will kill both batterys and i cant start. A isolator can seperate the two batterys when the ignition is off, so it always keeps one battery available for starting (ie. if my auxillary battery dies, main one will still be charged/ready because its not connected to the auxillary). I've heard battery seperators do the same thing....? Which is better/

    it all depends. the best thing to do would be to search. There are quite a few theads on the subject. In the end I ended up going with the relay method. Works Perfect

    it seperates the power from the main battery to the the aux battery with the relay. So the power is physically seperated. When a small amount of power is applied to the coil, the 2 join and the car charges the 2nd battery. I have the relay triggered by the ign. So that way the relay is closed(connected) when the car is in the on position.

    heres the relay im using
