Got a problem thats driving me nuts. I've been running the new GP-35 with an older Legacy GP30 as a MU for over a week and with the exception the rear coupler of the second engine opens without warning at times I've had no problems. But, I'm hoping someone can tell me why the system won't allow me to add a third engine (older Chessie TMCC U33 to the mix. The Legacy controller programs all three but the TMCC U33 engine won't start up with the other two.
When I program the U33 as the first engine, it starts up fine as does the second legacy engine but then the third legacy engine in the lashup won't start.
Anyone know why I can start any two engines but not three?
Joe
