Has anyone had problems when installing a DCC decoder in their Tug?

I've bought both Loadhaul and Mainline examples and have DCC equipped the former without any issues. The Mainline example works fine under traditional DC control, but when using a Lenz Gold, that is known to work, I can communicate with the decoder but not drive the loco.

The Hornby service sheet doesn't detail the wiring connections for the circuit board.

Any help appreciated.

When you say the decoder is known to work I assume you took it out of another runner? Have you tried it in the other 60 just to eliminate the decoder fully from the equation? Why not check the boards against each other?

Yes, I proved the decoder in the other 60 and have illiminated that.

I'm concerned about removing too many wires at once from either board without a wiring diagram. Having metered out the NEM socket I can see that the track and motor feeds are correct according to NMRA RP 911.

Once I've worked out what the other 14 wires do, I'll consider swapping out the board.

I removed the board from the class 50 I have to return to hornby and made my own drawing of what went where. Do it for the one you know to be ok and then compare it to the "duffer". You could try emailing hornby for a wiring diagram.

Try turning the plug around so that pin one, orange wire, is in the opposite hole. Do the lights work and is pin one marked on the board. There has been the odd model that has been wired up backwards so that pin one as marked was actually pin 5 but even that was wrong. Or in the case of the early Atlas diesels nothing was marked so you guessed. If you do plug it in the wrong way round the loco should move but the lights if fitted won't work then it's just a case of turning the plug around and it all should work. If not well, ring Hornby or hard wire in the decoder.

I know this is going off thread but has anyone sucessfully re-wired their tug lights to give a more protoypical appearance, I was going to use one of my TCS A6X Drop in 6 function decoders, so that I could operate the tail lights independently and switch to day/night settings as well, but theres so many wires that its hard to determine what they do??, so I gave up. I may wait until express models bring out their 8 function conversion. The Bachmanns seem much more straight forward than the Hornby's.

I don't like the switch idea for going from day to night setting. I know they have to be discreet as to where to put it but as with a lot of loco's they aren't going to like being handled all the time so maybe an alternative place woud've been better or not bother at all as the hornby ones don't really show and the bachmann ones seem to have a blown sidelight.

I think the sidelights are wired in series with the day/night headlight. So, with replacing/modifying the LED board in each cab it is not straightforward. Does anyone know what all the other components on the main PCB do? There seems to be far more than either Bachmann or Heljan use.

From what I understand the wiring from the circuit board to each cab comprises common, tail lights, day mode and night mode.

By the way, Hornby suggest I return my Tug to their repairs department. In the absence of a wiring diagram I think I'll do just that!

FOR 37197 re lights

If you go on the RMW forum http://www.118go.co.uk/rmweb/index2.htm
DCC section
and the thread named " Automatic or manual lighting control no choice! "
It may be of some help to you

Cheers for that Jeff, but its not quite what i'm after as the wiring seems to be more complex than a Bachmann or Heljan, both of which I have successfully wired to give independent operation of head/tail lights with very minor modification. Because of the way the lighting is set up with the circuit board at each cab it's hard top determine as to what each wire does, I was going to take out the pcb and use one of my TCS A6X Drop in 6 function decoders so that I can switch between day/night without using the switch and operate tail lights independently. Has anyone performed this successfully
