MTH PCC Trolley problem

My PCC had a issue this year too.  The rear truck "Elevated Ground Mount" bung broke off of the truck.  It looked like was connected because the wire was not broke, but the mount had sheered off at the base.  Thus, in the turns it would randomly stop or otherwise act funny.  I struggled with this for 2 seasons before finding it this year.  

You may want to see if the trolley will power with just the front and then just the rear truck on the track.  That is how I realized that something more was wrong with mine.  I held the engine so only one truck at a time was on the track, which also allowed for me to wiggle it to find a loose connection.

To fix it my issue, I just ground off the rest of of the ground wire mounting bung, drilled a hole for the wire, soldered a highly flexible wire to the truck, then, soldered it to the ground wire.  So far so good.

(Forgot to add)

My PCC is a PS2 Washington DC Trolley.

Good luck with yours.

The problem is I take it home to run and it runs great but when I bring it back to the layout with the Christmas tree, it won't work?
