LTSR_NSE Posted June 29 Share Posted June 29 @Brew Man The loco doesn’t contain lights, so should only have motor & pick-up wires attached to the socket (however if 5th & 6th pins on socket did have pointless/unused trailing wires attached - they could be removed from loco with socket!) Once 6pin socket is removed & replaced with a 4pin there would be no extra wires. Link to comment Share on other sites More sharing options...

Is this not correct? If I am correct then, after snipping the socket away from the 6 wires, 2 wires can be moved out of the way, (or removed/unsoldered from their origin, either way they will need to be dealt with) leaving the 4 wires of interest to be connected to a 4 pin socket. Is this not so? Edited June 29 by Brew Man Link to comment Share on other sites More sharing options...
LTSR_NSE Posted June 29 Share Posted June 29 I believe Hornby are using 6pin sockets over 4pin (where space allows) in order to support their newer (HM7k) decoders. Just because a socket allows for up to 6 connected wires, I wouldn’t assume unnecessary ones to be included, as it would involve wasted material & labour cost.

As I said, I have never seen inside this loco, but if there are 6 wires then it is as I said. Blimey this is hard work. Link to comment Share on other sites More sharing options...
Fishmanoz Posted June 29 Share Posted June 29 (edited) Doesn’t the 6-pin socket have only 4 wires attached, as per Ian’s description on page 1 (he describes them as motor wires). Edit: Oops, thought I was replying at the bottom of page 1, I missed the intervening posts on page 2 above. Makes you wonder why they used a 6-pin in the first place.

Going Spare Posted June 29 Share Posted June 29 The website illustration of R7150 shows 6 wires: Brown, Grey, Red, Black, White & Yellow. Link to comment Share on other sites More sharing options...
Brew Man Posted June 29 Share Posted June 29 (edited) Well according to LTSR_NSE it is likely to make them compatible with 6 pin HM7k decoders, which is quite believable. GS responded as I was typing. Edited June 29 by Brew Man Link to comment Share on other sites More sharing options...

They need to be just got out of the way. Just cap and stow wires 5 and 6 if present at the 6-pin socket. Link to comment Share on other sites More sharing options...
Brew Man Posted June 29 Share Posted June 29 Thanks, Rob, I'm sure that will be helpful to Ian should he wish to do the job himself. Link to comment Share on other sites More sharing options...

Note that comparing 4 and 6 pin decoders it is not just a case of clipping 2 elements off the socket as the colours and pin-socket don't align. It will be a rewire job.

Fishmanoz Posted June 29 Share Posted June 29 Might I refer everyone back to Ian’s on page 1 where he reports 4 only wires to the 6-pin socket (not incl white and yellow), then I refer him to Brian Lambert for the 4-pin socket arrangement for his re-wiring job?

Is this not so? That was my dillema at the beginning of this thread - "I now have my Ruston & Hornsby 88Ds and the recommended decoder which is R7150 and there is my problem. They are both 6 pin and while 1. is clearly marked on the decoder, there is nothing on the loco or blank, ( have studied them under a microscope and there is nothing there). The six pins on the decoder are 1. Brown 2. Grey 3. Red 4. Black 5.White 6. Yellow on the motor it is 1. Grey 2. Brown 3. Black 4. Red with 5. and 6. no wires attached." - this was adequately explained by several members and I was successful in fixing the problem. ps I had the colours wrong which were also corrected Edited June 30 by Aussie Fred 1 Link to comment Share on other sites More sharing options...

As to the decoder I would stick with 6 pin it gives you more choice of make. If you were in the UK there are many that are smaller than the Hornby offering. Funny I rewired all my Hornby 4 pin decoders to 6 pin. I suspect on this you are going to need "stay alive". Link to comment Share on other sites More sharing options...

Hi there, I'm glad you sent this cause the 6 pin decoders have got the Orange and Grey wires mixed up. So I ended up hardwiring the decoder to the motor itself and worked. I've also got a City of Sheffield train with decoder and sound included but it won't work cause I bought it through Ebay I guess this was produced by the guy i bought it from. So I was wondering how do I get to reset the decoder. Link to comment Share on other sites More sharing options...
Fishmanoz Posted July 11 Share Posted July 11 Are you telling us the decoder has the grey wire going to pin 1 on its plug and the orange to pin 2? What brand decoder? To reset a decoder, write 8 to CV8 on the programming track. Link to comment Share on other sites More sharing options...
Ian-1301567 Posted July 11 Share Posted July 11 Yeah I bought 2 6 pin decoders made by Hornby and the Grey wire was in PIN 1 and Orange Wire in PIN 2. When you say CV8 what do you do. Are the wires in attached to the Programme Terminals on the DCC Controller and train placed on track and Controller set to No.8 under the Address area.

LTSR_NSE Posted July 12 Share Posted July 12 @Ian-1301567 what DCC controller do you have? To write (modify) CV values the controller would need to support that function - does your controller’s manual not mention this function? Link to comment Share on other sites More sharing options...
Ian-1301567 Posted July 12 Share Posted July 12 Well the DCC Controller is the Hornby Elite Controller. Link to comment Share on other sites More sharing options...
Ian-1301567 Posted July 12 Share Posted July 12 What are the step by step instructions to Modify the CV Values cause the Program side I can't weight up whether it works or not has there is no power in the line when connected to the Program leads area of the DCC Controller as when the leads are placed in the Track side connects the line is live. So can you not modify the CV Values on the live track. Link to comment Share on other sites More sharing options...
Brew Man Posted July 12 Share Posted July 12 (edited) On the Elite you have two sets of connections at the back, not counting the auxiliary outputs. One is for the main, (running) track, the other is for the programming track. They are both live except the the programming output can only source a small current, not enough the drive a loco. It is the programming track outputs, connected to a separate piece of track that you use to set/alter CVs. What revision of the firmware do you have? the latest is ver. 1.45. If yours is earlier than that you should update it. The 1.45 manual, if you don't already have it is available here to download, and it tells everything about reading/writing CVs.

Ian-1301567 Posted July 12 Share Posted July 12 I'll to check that but I'm sure that when first switch on the Controller it goes through the process on switching on it comes up with Version 1.45 on the display. Link to comment Share on other sites More sharing options...
Brew Man Posted July 12 Share Posted July 12 Well that's the latest version then. Do you not have the user guide that came with it? If not, as I said it is freely downloadable. Link to comment Share on other sites More sharing options...

And do you just connect the 2 wires that come off the lighting unit to the Yellow and White wires. Link to comment Share on other sites More sharing options...
