PLEASE HELP
I was running my ho dcc ready acela  train on dc  everything was fine. I removed the shell to see what type of dcc decoder i needed  there was a (cap,plug) whatever on the socket i removed the plug  found out it is an 8 pin  i put the plug back in the socket  I put shell back on ......... NOTHING WORKS..... NO LIGHTS  NO HUM  NOTHING. what did i mess up? If you crank the throttle wide open  and set the wheels down on the track all kinds of sparks  like a short ..... not like regular sparks when you set it down normaly with power applied .  Its not the controller or track  other locos run fine
HELP!!    i just spent over 200.00 on this  I like it but doggone  someone please tell me what i did wrong
thanks

first time posting ....I have a bachman spectrum Magnum  controller  that came with a used ho ACELA dcc ready (no decoder) train set . The problem is it only goes one direction, when you move the switch to reverse the engine it doesnt move . i changed engines  still same problem. I changed controllers  both engines work fine. I was going to pull the cover off, but it takes a special tool to remove the screws (which i dont have). could this be a simple fix or better off to buy new one.  Ive never seen the inside of one , so i dont know if there is a board gone bad or wire has come loose . Any ideas or help would be great
thanks
