Loco Address

[Meld]

Hi,

I have just had a class 25 repaired when the loco was sent back to me after having a new decoder fitted the repairer told me the address is 3 which is the standard address for locos, so I wanted to change it to 69 I have a ESU command station and it is pretty straight forward to change the address, except when I program it on the programming track all changes seem to have taken place but then when I place it on the track it will not run, then if I change it back to 3 all is fine and it runs, has anybody got a clue what is happening.

Have you made sure the track and wheels and spotlessly clean? This can make programming difficult.
You could also try the ‘program on main’ function as it will give the programming a bit more ‘oomph’.

This may be due to the way different DCC controllers regard 2, 3 and 4 digit addresses.

Address 3 (for example) may be coded as 3 or 03 or 003 or 0003 I think and your controller may regard address 3 differently to the way the decoder is set.

Try resetting the decoder. Often done by sending a value of 8 to CV 8 but the reset value can vary between manufacturers.

Thanks Steve M I tried programming on the main and that seems to have done the trick, took a couple of attempts though.

There is one make of controller (can’t recall which without referring to my files) that appears to have done the deed on screen but is a bit tardy in actually completing the programming action.

In this case all that was required was to wait a bit between steps and especially at the end so the controller could get its programming ducks in a row.

Glad it worked. It’s a technique that I have had to use with some TTS decoders and always worth a try.
I also have an ESU decoder tester which can also be used as a dummy loco for programming purposes and also helps to check if I’ve fried the decoder or not.
