short update I called tinman hes really nice , the way I wired is correct . I do not have a extra ground in the center switch.. though He recommended since I am using tmcc with the power-master to run two wires from behind that to the engine when it slows or stall at the speed it ran on the upper level.
When I do and it stalls adding the extra wires from behind the power-master did not help it move ,so I will have to keep trying heres a picture of the area that it slows in. upper level fine,
Second problem is if I make the engine run faster sometimes at the two switches it will make the frount trucks derail... the center power part where the moving switching part is higher ...Tinman did not think taking them apart and lowering them would help. (center power strip ) . any thoughts on that would be appreciated...
sorry for the poor pictures with my old phone camera.
