An engine shorted on a switch in my engine yard on fixed2 block with tender spanning onto the Var2 mainline. The Z4000 red light came on, I powered down, I moved engine out of the way. Powered back up, I then back a ps2 engine out from the yard (fixed2) under command control onto the mainline (Var2) and then noticed I have no control, no dcs signal on the var2 mainline, but engine is running (run away actually). Powered down, open tiu, check the fuses, all ok, put together, now var 2 is completely dead, no power at all. Fuses are seated properly. Rev. L tiu, channels set to fixed, on, on, fixed, both Z4000 handles have power. Suggestions? New tiu needed? Thanks in advance.
