Hi Group,
Doing up my first Rapido loco with their Mo'Power "keep-alive" capacitors. I know you can hook up a PB-2 or a TCS Keep-Alive to Pin 16 (+) and Pin 20 (-), but seeing as this loco already has a "keep-alive" in it, I figured maybe I don't have to add one.
Got the module and speaker in, but the Mo'Power seems to be more like No'Power.

Has anyone done a Rapido loco with the Mo'Power unit or am I blazing new territory here?
For reference, this is a GMD-1 and here is a so-so photo of the stock set-up, with the Mo'Power unit highlighted. I can get better photos, just tell me what you need to see!
Thoughts?
