My money is on option 1 Nigel! 

Thanks for the suggestion Nigel - I tried your suggestion for putting function 2 as function 10  but it didn’t seem to have any affect. I think this may be beyond me - I’m really grateful for people’s help but I’m as confused as ever and I may have to leave it as it is rather than cause further problems by trying to do it and getting it wrong.

Thanks everyone for all your help - I think the best thing to do is to move the lighting from F2 to F10 which is already latching - is there anyone who can help me on how to do this? I haven’t tinkered around with CV’s on DCC so I really need a step by step walkthrough on how to do this. It’s on a gaugemaster prodigy express controller. 

I have recently got a new RealTrack 156. Came DCC fitted and function 2 is for the interior passenger lighting. When I press and hold F2 the lights come on but I can’t get them to stay on. Realtrack tell me the function may need “latching” but I don’t know how to do this and am worried about effecting other locos. I am using a gaugemaster prodigy express controller. Can anyone be of any help?

This guide is very useful  -  http://www.youchoos.co.uk/Index-Detail.php?L1=Detail&Item=MX644

 

You do need to attach the stay-alve wires before fitting the decoder as they are on the side that faces the PCB.

 

There should be pads on the loco PCB for the speaker wires somewhere. No doubt someone with a 37 will be along with the info/pics to help you.

Thanks Izzy - that's really useful

Cheers, David.

If thats a current one it should have speaker connection points on the PCB - probably labelled SP+ and SP-

 

As for the wire - nothing too hefty needed, A fine multi stranded cpooer wire will be fine

Thanks for that Phil - much appreciated!

It is a current model (MMRG Ltd edition) so I'll look out for those. After wiring speak to the PCB points on the loco I assume its just a case of attaching the capacitor directly to the chip and I'm good to go. Are you able to help with where the wires should be attached to the speaker? (see picture)

Cheers, David.

Hi all.

I've been modelling for a while but wanting to take next step and fit sound to a loco.

I'll be getting a Bachmann class 37 shortly and I've already bought a Zimo MX644D decoder with stayalive capacitor and a Zimo 3D speaker.

I'm confident in fitting the chip to the loco but I'm not sure how/where to attach the capacitor, and also unsure of where to solder the wires to connect the speaker. Also not sure on exactly what type of wire to use.

If anyone could be of help it would be greatly appreciated - I could just take it to my local model shop (The signal Box, in Anstey, Leicester) but I'd love to be able to learn how to do this for myself.

Cheers!
