Is it just me or does anyone else have problems with the Digitrax Zephyr being to sensitive to shorts. I can get my PRR M1a and my Genesis big boy to run using the Zephyr but it takes quite a bit of fiddlng with them to clear the short and there is no way that I can place both locos on the track and get the short to clear out. Of course I programmed both locos to a different address. Will setting the opws from 1/8 sec to 1/2 sec help this? I don't want to take a chance on burning anything up by doing this.
