MRC Control Master 20 Replacement - Walk Around Throttle

This is a solution to keep your Walk Around Throttles without dependency on access to MRC Control Master 20 power stations. Part one with the intention of doing more videos on this application...using a PLC with Pulse Width Modulation (PWM) to control DC (analog) locomotives of any size.

You don't happen to fix the control master throttle controller do you? I have 2 units, iv narrowed it down to the hand held throttle as being bad..I plug in one remote and the trains run fine, I plug in the other and nothing, the direction work on it though as I can hear the relay switch over in the power box..and, the momentum light illuminates..but nothing from the pot ..

I built this for a friend, that is the limit of my involvement.
