I believe the 4116 rams use three different voltages. If any wires were
mixed up when istalling the switcher they could have taken out a lot of
stuff. Check your voltages on your rams. Don't leave the game on very long
when testing untill you know you have the right voltage. Max

 Anybody have experience with these types of failures? What if the
