I  installed a shurpower 1315 isolator. It is so simple, I don't know how  I
messed it up.

I hooked up main battery + to one terminal, Aux  batter + to the other
terminal.  I left the 3 little switch prongs  alone, as I don't need it
manually switchable, just want it to  intelligently charge the aux battery.

After a few days, my aux battery  was dead and I realized something wasn't
working.  I checked voltage  at the terminal from the main battery, about
12.5 not running, around 14  running. A little hard to get it exact on a 50
volt scale analog  meter.  Only 5 volts at the other terminal, running or
not.  I  realized the main and aux battery + wires were connected to the
wrong  terminals, so I reversed them.  Same result immediately after.   I
would have expected to see 13+ volts going into the dead battery.   Is that
right?

There isn't a ground terminal on the isolator, so I  just put a small screw
into it screwing into the battery box metal and  thought that would be
sufficient.

Dave, you did not read the directions  carefully.  Leaving all three pins
unattended is your problem.  The  third pin from the top is to be grounded for
the 1314 to work.  Only the  first and second pin are optional.  I just finished
installing one in a  clients van a few days ago.
