Hello all,  I am a newcomer to HO and bought a DCC set with EZ Command
and after opening the box and setting it all up; it all worked just fine.
The set has 2 diesel engines and I ran each of them for only about 10 minutes total and then put them away (for about 8 months) until I had time to set up a table and get serious about a layout.  Tonight I started back into it and now only one engine works.  The other is dead as a doornail.  I tried resetting the DCC address but got no response at all. 

Then I recently bought another Bachmann set that is DC so I took out the power pack for it and connected to the track.  Still no response but now at least the headlight came on but nothing from the motor.

Anyone have any suggestions or do you think I might have fried the motor?

Thanks!
