GG1 and Super O switches

[alcatalfamo]

My GG1 shorts the rail when it runs threw a super O switch.  Has anyone had this problem and what did you do to fix it?  Any help well be greatly appreciated!
Thanks,

Is the GG-1 stalling or tripping the circuit breaker?
If it is stalling, it is losing power from the track. Shorting out might happen at the curve pieces of the switch, to find out you must run the GG-1 real slow and let it stall, that is where your problem most likely is.
