Hi all, Got kind of an unusual problem pop out of nowhere on me. i have the Digitrx DCS-100 booster on my layout and three locos: a Kato UP & Amtrak, and a Atlas SP. All of a sudden tonight, i'm getting these random power loses on the layout. It's a small layout, still under work. Only recent changes was this evening I wired two turnouts to their atlas switches, and a few days ago I soldered just 5 rail joiners, but after that I tested running the locos right on the joints and everything was running fine. I can take my SP loco and run it over a stretch of track and it see it kinda die out a bit, lights flicker, and stuggle for power. It'll make it through, or sometimes not and I have to help it along. But I can reverese and go right back through the same area it just died with no problems a lot of time, only to have problems someplace else. I have most of the track blocked of with isolator joiners and feeders on each block so there's adequate power being supplied. I tried the quarter trick and the booster responds to a short everywhere I have these power loses. I thought maybe the soldering but it's even occuring on other blocks that I didn't touch yet. The Amtrak and SP have the issue the worst, the UP will have flickering lights but doesn't loose power totally and keeps on chugging along 95% of the time. And the slower the loco is going, the more likely it is to die totally until I even just touch, or give it a little push. I'm totally lost on what's going on. It seems like the power is fluctuating but I can have two locos in the same block, one die and the other not. Funky, huh? Hope I haven't totally confused anyone. Anyone have any ideas?
