Well, that assumes that the battery in there has been put in correctly.  As
I understand it, Oliver has already established that the battery has been
connected as if it's negative ground (and you don't need a voltmeter for
that, just look at the battery markings).  Oliver's just worried that it
shouldn't have been connected that way.
