Tts class 47 and bachman

[Darren C 1]

Hi,

 

relatively new to dcc, and modelling generally.

have a class 47 Hornby tts loco.

been running with Bachman ez command...no problems.

upgrad d to Bachman dynamics, loco won't run...just as if it is not there. 

Any ideas please?

As this is a Hornby forum, I doubt that many on here will have used Dynamis controllers. I haven't even seen one, to my knowledge!

Why won't the loco run -

First of all, have you wired the new controller up correctly, so that power is getting to the controller and the track?

Have you entered the correct code for the loco? The dynamis could still be trying to use the default code. (On a Hornby, that is 003).

 

(edit for a typo)

Thanks for the suggestions....other Loco, including tts flying scot work fine.

wiring is fine.

cant even change address of class 47, where I have done so again with other locos.  It's as if the loco does not exist. Can't control it, I gave no idea. Star on address 7 for now....maybe should try a different address using the ez, then see if that works on dynamics?

The Bachmann Dynamis is more featured than the Bachmann EZ. As an analogy, a bit like comparing the Hornby Elite with the Select.

.

Try using the Dynamis to reset the TTS loco (write decimal 8 to CV8). Then readdress the TTS to the address you want for it using the Dynamis.....then test again.

A very long shot... but, maybe check the wiring inside the loco as one may need soldering back into place?

Especially the wheel pickups. Open it out and check those.

At least it will eliminate this check once done and confirmed. So simple to fix. As I said, a long shot, as it has worked prior on another controller.

Hi

again thanks for the response. And sorry for my appalling typing.  Don't think it is a wiring problem since the loco works fine on the ez, but I will try changing the address as soon as I get a chance.

thanks

Something I have used in the past is programming on the main (POM) which I presume your controller can do.

 

According to the rules you cannot chamge and address using POM but I have found that you can write to CV1 without any hassle. You cannot generally readback to check though.

 

If trying this make sure the loco being programmed is the only one on the track, and that includes removing any accessory decoders you may have wired to the track.
