Thank You.

Thanks for all the advice.  For now, I will program in the operating mode and avoid the cost of the booster.  If it continues to be a problem, I'll buy one.  Phil

Sid, I did read this thread.  That's how I at least got the address changed.  However, the thread never finished about using the programming mode.  Do I really need a booster?  Phil

Thanks for all the replies and offers of help.  Hunt, the item number for my Baldwin Modern 4-4-0 is 80126.  I use the Digitrax DCS 100.

Another update.  If I program on the main line (no other locomotives on the track) in the operating mode, I can reset and I can assign an address.  However, when I go back to the programing track and try to display the address, it gives me either 0000 or 6282.  Remember, I don't have an issue with other locomotives where their programming addresses are fine.  This may have to do for now.  At least I can run the trains and assign them addresses.  Weird!!  Thanks for trying to help.  Phil

Wounded Bear.  Thanks for the thread.  It enabled me to at least get back to "03" to run the locomotive.  That's progress.  However, I still can't program any of the CVs.  I tried resetting several times and inputting a new address, but to no avail.  I have another locomotive (an Intermountain F7) that is doing the same thing.  The common denominator is that they were both run on a DC-powered track.  I'm guessing this has something to do with the problem.  My other locomotives that didn't run on the DC-powered track are ok.  Phil

Richly,

Yes, it has sound, so I'm assuming the decoder is plugged in.  Phil

Thanks for the responses.  It's a Baldwin 4-4-0 with DCC on board (Spectrum).  I had no issues on my previous layout.  Also, when I set CV8 to 008, I did recycle the power and there were no flashes.  Definitely not working on "03."  I definitely may remove the shell and check the connection, however, when the train is on a powered track, it definitely has sound like a locomotive at rest.

Guys, I think I screwed up.  I ran my Bachmann 4-4-0 on full DC before I was able to wire up my Digitrax DCC.  Once I did wire up my DCC, I could not obtain my locomotives address on my programming track.  I followed all the instructions in the manual including resetting to factory settings (CV and unlocking the codes (CV 15 and 16), but nothing resolved the problem.  I tried "00" and "03" as an address and nothing.  Do you have any suggestions?  Is the decoder fried?  Thanks in advance for your help.  Phil
