I noticed recently my sw 800/ 1200 has been running strange. When going slow it will stop and not start going again untill I give it a little push. I took the body off of it and slid the frame down the rails to see if still did it. It ran fine that way. I'm guessing that I have some kind of power pick up problem or possibly when the motor is under load at slow speeds that has a place on the comm that brushes aren't contacting right. The locomotive isn't that old and only has 4-5 hours on it so it shouldn't be having problems this soon. Any ideas?
Yep! Here's a site dedicated to DCC, but has a great how-to for improving LL switcher pickup: http://home.mindspring.com/~filker/NLLSW9/SW9_DCC.html The part you need is at the bottom part of the page.
