For higher reliablity, use a diode isolator. Please see Section 7.1.9
in the Car and Deep Cycle Battery FAQ on www.batterfaq.org for more
information and other alternatives.

I use a combiner - a relay triggered by connect and disconnect voltages. It
works, though I'm not ecstatic about it. If I were doing it again I might
consider the Xantrex Echocharge, which will pass a small amount of current to
the starting battery.

Looking for suggestions on isolating the motor cranking battery from the
house deep cycle batteries both being charged by one alternator & wind
generator.
