If you have a nine volt battery on hand, that is all you need to test the device and the LED. Don't us any other power supplies: Even if you hook up the leads out of sequence, no damage will happen to the device..... Take your time... try different wiring connections.... 👍

Just tried that. It worked perfectly! Looks like the board is fine after all. Now I just have to figure out how to configure it so it works in my locomotive.
