Ok i have the shell off,  When i apply throttle to the engine the engine revs up but doesnt move,  i poke at the motor when its in the forward position and it moves jerkingly,   while in the reverse position it runs like it should, very strange....and i tried dc.   only has enough power to start up the loco

Did you figure out what the problem was with your S4?  Mine is having the same issue.  Wrote B tech but no reply yet.

Please post back.  Thanks
