Bad Pickup Roller??

[dougdagrump]

Just a quick & simple check of the p/u rollers is to put a short strip of electrical tape on a center rail, straight section preferrably, then slowly drive the loco onto the tape. If it stalls that pretty much indicates that only one p/u rolleris operating correctly. Turn the engine on it's side and use a little contact cleaner, WD-40 etc on the roller pin & inside of roller while turning it with your finger tips. That should help to clean anything out that mite impair the conductivity, afterwards if you have any put in a couple of drops of a conductive lubricant.

Hope this helps.

 I have a Weaver  RS-11 diesel that will stall on my Lionel 022 switches, not all, but enough at slow speeds.  The track is clean and so are the rollers. Track connections are good.  I checked for loose wires and found 1 that was loose from the sounds control knob.  I soldered that and couldn't see any others loose. Didn't help.  I  do notice 1 roller sparking for a lot of the time.  Could this be bad or what else??

Thanks in advance.
