Bachmann J72 31-062SF not working with Select Controller

[Mike65]

I'm new to DCC and am having a problem I'm hoping someone can help me with please?

I've just bought a brand new Bachmann J72 0-6-0 with sound fitted (31-062SF) and I have a factory upgraded new Hornby Select controller to V1.6.

On taking the J72 out of the box and putting it on the track as '03' on the controller, it went slowly round. I then tried to assign it a new address, but it will not take it and will now not move.

The hornby Select says that the red light on the controller should flash 7 times, but with the J72 on the track it only flashes three times, so not sure if the loco is compatible with the Select controller?

I have another hornby DCC sound fitted loco that works fine.

If you could help it would be much appreciated.

Thanks.

Mike

Suggest you starting by writing 8 to CV8 which will reset all decoder settings to factory including putting the address to/back to 03. Then try again.

Make sure the J72 is the only thing on or connected to the track otherwise you will reset everything.

[Mike65]

Thanks Fishmanoz but I tried that and it didn't work.

It is the only loco on the track.

Any idea which sound decoder is fitted to that loco as other forums report that some Zimo sound decoders are playing silly beggars with various controllers. Zimo apparently aware but not yet responsive.

The Bachmann leaflet with it says its a Next 18 ESU Loksound Micro V5DCC.

I've now managed to give the loco an arbitrary address e.g. 33, then it will go round slowly and after it stops, does not start again and I have then to re-set the address to a different one e.g. 22 and it will start again??!!

Very frustrating and being a newbie I'm wondering have I not done something.....

From what you describe Mike65 it sounds like you are doing nothing wrong. The Loksound from my experience seems to not be very tolerant of a bad DCC signal compared with a Zimo and even a Hornby, so it could be that. What it might be and I am assuming it has a Next 18 decoder in it, is the decoder is not properly making contact with the socket. On my Bachmann 812 I had all sorts of issues, Rails who I bought it from, suggested taking the decoder out and putting it back in again. That didn't work until I cleaned all the socket pins with alcohol. I have had it happen with another Next 18 decoder in a different loco. Obviously if you don't have a Next 18 decoder then ignore what I have said. If all else fails and this is expensive, is buy a normal decoder and see if that improves it. Then at least you will know what is wrong. LaisDCC do decoders which are quite cheap and are perfect to just test out locos. The other thing to check is that someone hasn't fitted "keep alive", that makes programming difficult.

Don’t fret about the number of flashes, more important is does the given address stick - must be within the range 1-59.

[Mike65]

Thanks for all your help. I'll try a few things tomorrow but rather than fiddle about with decoders etc, I'll return it as I don't want to negate the warranty.

[Fishmanoz]

Agree with only doing things not involving removing the decoder and return under warranty if unsuccessful. However, do suggest you report to your supplier that a forum user (Colin) has reported the need to clean the pins and socket of a Next 18 decoder to get it to function correctly, along with the second reported unable to program problem.

And an observation not related to this topic - oh dear, DCC TT:120 with Next 18 sockets - here we go with a problem before we even start.

@fishy

It is a well known problem that Next-18 decoders have to be firmly plugged in. Add to that manufacturing tolerances twixt socket suppliers and various manufacturers decoders and it is as you say a problem before we start.
