Years ago I converted a dummy Atlas 2 rail GP9 to 3 RS with TAS for sound lights and coil couplers.
After being un used for years the engine sound just starts running when ever track is powered.
Nothing else works. Doesn't respond to CAB control. Sound won't turn off. Horn sounds once in awhile
on it's own. Won't reprogram.
Any ideas of what the problem is ? I'm thinking the R2 board. I've been away from the hobby for awhile.
Thanks
Joe
