Those strips are very touchey. Too much spring pressure from the contact strip to the truck and it will raise the truck away from the frame, too little pressure and no electrical contact. You might try using a conductive cleaner on these contact points. There is a very good product made by Areo-Lube ( I think I have that right). It is a cleaner and contact lube, works very well, I use it every day when doing DCC installs. If you need more info about it I can find you a link to a site where you can get it.
