Well ok, that's what I ment by 'bottom'. They don't have labels, but mine
has a + center. You can carefully check with a voltmeter, but DON'T short
the probe aross the jack. You could also pop it open and look at the wiring
inside. I simply looked at the ratings on the battery charger and instead
of trying to adapt the plug, went to the thrift store and bought a simular
transformer with plug for $3. On my last charge, one battery didn't take a
charge, so I pulled them out, but charged them while still connected to the
controller. I think I have a loose connection. You should still open the
case when charging because of heat buildup.
It's a great little unit, they really lack the documention and the
description on the box is misleading. I run over 150' of wire at the end of
the 30' to get to the far pads.
