On a Crest lithium battery back (the kind used with Aristo onboard train engineer), which wire is positive polarity and which is negative? I know that black is usually positive, but I want to make sure.
Thanks,
Arthur
Red is almost always positive in most parts of the world!

Also invest a few bucks in a multimeter! You can find them as cheap as $4 at HarborFreight. I can't imagine working on electronics without one.

Not entirely sure how I made that particular mistake. Wow. Anyway.
I apologize for giving the impression that I've never heard of an electron before.
The particular project I'm working on is the G-Scale Graphics basic Critter Control, which is a manual control system for battery locomotives. I've finally got it put together, and it works in a manner most charming.
