Thanks Jim, I'll check that decoder.  I know it's a Digitrax Z type.  Would that be a non-silent decoder?  I'm not looking forward to taking this thing apart again!!! &%%&$$*

I have found two websites that have instructions for decoder install to the Spectrum DCC ready 0-6-0 dockside switcher.  One website says to remove the two yellow capacitors on the motor, and the other makes no mention of removing them.  Any thoughts, or does anyone have any experience with a decoder install and leaving them in?

Thanks! Jim
