I recently got a new-in-the-box merchandise car from the Lionel 2013 or 2014 catalog as mentioned in this thread. I'd like to add an ERR Mini-Commander as my layout doesn't have any operating track sections.
I see a couple of you guys have added a Mini-Commander to these cars. Inside the merchandise car I see a small circuit board that looks like a half-wave rectifier driving a constant voltage regulator for 9v DC output to the small motor. Which Mini-Commander did you use? Looks like 3rd Rail is currently offering the ACC, EX, and II versions. I'm presuming you drove the small motor directly from one of the Mini-Commander's HC outputs (or is an inline diode needed?). I've installed AC Commanders in various engines, and put Mini-Commanders in my post-war milk cars, so I can probably figure this out, but any tips or hints on the best approach would be appreciated.
Thanks!
