Rear pickup roller has no power

Norm, you can do this.  Open up the engine and follow the roller and you will see a broken wire.  If you do not see a broken wire and the wire is attached to the roller, follow the wire to where it should go into a wire nut and redo the connection.

This one should be the same, Same wheelbase, Same year, same electronics inside.

Just click on the Picture of the book on the linked page.

Thank you Marty for your advice and thank you Russell for the on line manual. This will help me alot. Thanks again.

Norm, if all looks well when you check the loco, unscrew the power wire (center rail) and check for continuity from the wire end to the wire nut joint. Sometimes the insulation hides a bad connection. Ran into this a few times. 

I took the engine apart this morning and did not find any loose or burnt wire connections.Everything looks good so i wiggled all the connections too see if it would correct the problem.I ran the engine again to see if it was just a loose wire but it still stalls on the switches. Without proper wiring diagrams i`ts hard to follow where the wires go . Train DOcter i will  look for the wire to the center rail next and see if that is the problem. Thanks for advice.

I had a Weaver M1a that had the same problem.  Surprisingly I sprayed the suspect roller with WD40.  The pin holding the roller was rusty.  A lot of rust was visable as the WD40 was worked into the roller.  Thumb-roll the roller after applying WD40, then clean the WD 40 off the roller with a soft rag, apply a few drops of light oil.     Something else to check. 

Edit/Add:  I have an Atlas RS1 diesel that had problems stalling.  I eventually cleaned all the wheels with a cleaning solvent, worked fine after the extensive cleaning.  

Did you use a continuity meter at the work bench to check out continuity between both rollers? here'a an easy way if you don't have a meter.... park one roller on a piece of tape on the center rail. the other roller should fire up the engine. repeat with the other roller.

Kind of sounds like you've already determined  the rear roller is the problem.  That should be an  fairly easy to fix even if you have to  jumper each roller with a piece  of wire.
