Lehighline,
I verified the short before I sent my TIU to him. We'll see what he says after he works on it. I just wish there was somebody in the St. Louis area I could take my problems to so I wouldn't have to send my problem loco's or TIU's by UPS or USPS to get them fixed. As far as I know I'm the only one who uses O scale MTH DCS in the area.
