Hunt,

Thanks, I do remember people mentioning this type of situation in the past.  I checked the trucks.  The front truck has the insulated wheels on the opposite side of the insulated wheels on the back truck, just like the drawing.  Does it matter which side the insulated wheels are on for each truck?  I speculate that what matters is only that they are opposite.

Any other ideas?

Thanks,

Happy Holidays Folks!

I have a Digitrax DCC setup (command station, booster, throttle).  Santa delivered a Bachmann 2-8-0 DCC steam engine to my boy for Christmas.  My layout right now is a simple oval.  I've performed the "quarter test" around the layout and it passed.  I can run an analog engine using address 0.  I place the DCC steam engine on the track (by itself) and it immediately shorts the booster and it shuts down.  My throttle recognizes the engine because it shows on the throttle screen the factory programmed address of the engine, 3.

I've read in this forum and other places (though old posts) about the RF filters and in the past folks have clipped one leg of the capacitor to eliminate this problem.  The paperwork with the engine indicates that these filters shouldn't be an issue.  For grins I removed the tender cover to look at the circuit board.  It looks quite a bit different than the pictures I've seen online.

The paperwork with the engine does mention that there are RF chokes (in the form of capacitors and inductors) on the circuit board and that they can be removed.  Though it should only need to be removed for non-NMRA standard decoders.

At this point I have no idea what I should do next.  Is there more troubleshooting I can perform?  Are folks still experiencing this sort of problem similar to what was happening a few years ago?  Any help would be appreciated.

Cheers!
