Hi gang. Can anyone tell me what the polarity is on a Digitrax PX108 Power Extender? The unit has a black and a red wire. I want to use it with a non Digitrax decoder.

From the Digitrax decoder Manual V2-01-2014

So the RED wire is positive (+), Black wire is negative (-)

Many thanks. That's what I figured but you can never be too careful.
