I recently purchased an MTH DCS system to run proto sound 2 and 3 engines. I have it set up but every time I turn the power on I get a dead short. The set up is as follows power from Z750 using TIU Barrel Jack Adapter Cable to Fixed Input 1 and power out from fixed output 1 to track 1 lead to center rail and 1 lead to out side rail. Any thoughts or suggestions?? Any Help is greatly appreciated.
