Ok, I only need to change the address to my MTH GG1.

Do you mean I should open a new thread with that title?

 No no no - sheesh. I was able to reset and change the address on my MTH FA's on the program track of my PR3, just fine. Probably true they wont read, but I have no reason to read. ANd I was able to use CV17 and CV18 to set my own long address, not just change CV29 to make it use the cab address - mine are 300, and someone else at the club has a 300, so I made mine 301.

 The GG1 should be new enough to have some of the updates - the first run of MTH triple mode locos do have some issues, but with each reelase they've added additional DCC support. The older ones for the most part can be updated if you know someone or have a LHS with a DCS system. Updates weren't made available yet for all the locos though.

 My issues with the FA's and why I want to throw them through a wall definitely are not because I cannot program them.

If it is like the first generation SD70ACe, try programming CV29=38 on the main. These first generation MTH locos will not read CV or program on a programing track

Yup. POM only. Even with a booster MTH engines don't like programming tracks.

Welcome to the weird world of DCS. It's a lot like that planet in Superman that is on the other side of the sun, Bizarro World (?) where they do everything backwards from what we know and love.

Yeah, Tom's right, you need to check the documentation, as there must be some way to change the address from 3, even in the limited control you get over DCC functions with DCS.

If the MTH GG1 is HO then it's DCC compliant, although Sabastian won't be able to access many of the functions.  I also checked on eBay and the MTH GG1s are listed as "can be controlled in command mode with any DCC compliant command control system"

Sabastian, does the manual that came with your GG1 say that you have to do something (throw a switch) to make it operate in DCC?  And what DCC system are you using?

Looking at the blurb on the MTH site, http://www.mthtrains.com/content/80-2147-1, all you can do with a DCC system is access the 28 different functions.   You are not going to be able to read or change any CVs. However, you should also be able to change the address.

Possibly you should re-post your question with a title like "how do I change the address on my MTH GG1?"

If it has the MTH proprietary DCS system, it is not DCC compatible, and you cannot use a DCC system to change it.

GG1 Electric from MTH in HO - I can't neither read nor modify any CV's!

Hello dear community,

I granted myself an (expensive) GG1 made by MTH in HO.

I'm not sure whether this is THE super model for the money...but it's nice and the GG1 always pleases - it's in her DNA I assume...

BUT, placed on the programming track, once I set to read the CVs the DCC station short circuits! Even if I try on the PoM by modifying the CV the station blanks...what am I to do? The address keeps being #3 and I MUST change it.

Thanks for any hint.

Sebastian
