The paragraph below should have the word AUTOMATICALLY added as I've
done so below.

You can easily add a pushbutton switch to the 1315 to manually
connect the aux battery to the starting battery...useful to "jump
yourself" in the event that you left your lights on, cold day and you
want more cranking power etc.

>As Mike C. points out, the 1315 will not AUTOMATICALLY connect the
>aux battery to the
>starting battery/charging source (alternator) unless the voltage on the
