Thanks Brewski. Just to verify I am thinking correctly, The joystick controller only send low voltage signal, not necessarily Line voltage to the Master controller. if so what would be the likelihood of two Joystick controllers going bad versus two Joystick controllers. either option of repair looks like it will be costly so just trying to be able to pinpoint it as best possible. I was 100% confident in the first ones diagnosis, but after the second started acting up, it raised some flags for me.
