Thanks for the replies, seems I started a bit of a discussion... I've swapped the wires around using my novice soldering skills and all is well with the world again and my son doesn't think that Thomas is broken any more.

Yes, if your controller can programme CVs...

Asked question RE: re-wiring the motor... http://www.rmweb.co.uk/community/index.php?/topic/136765-swapping-wires-to-the-motor-to-reverse-direction/ Edit... Thanks for the replies. I've swapped the wires around using my novice soldering skills and all is well with the world again and my son doesn't think that Thomas is broken any more.

Following on from my post here where I'm asking about writing CV values as cheaply as possible it seems the cheapest solution is to simply swap the wires from the decoder to the motor. http://www.rmweb.co.uk/community/index.php?/topic/136741-cheapest-way-to-read-write-cvs-on-dcc-chips/ Can someone just confirm that I need to swap where the orange and grey wires are soldered to at the back of the motor? Presumably I need to remove the heat-shrink from the orange wire and just re-solder them the opposite way around?

To answer a question over other locos... We have a DCC fitted Percy (R9288) from Hattons with one of their own-brand 8-pin chips which works perfectly although we didn't try the reverse running as we didn't have to and it's currently wrapped up for another week as a birthday present so can't easily re-test right now but I've no reason to suspect a fault with the controller given its operation during test. I'll try to re-test Thomas on DC this evening and open him up to see how easy the wire swap will be and if my poor soldering skills will be up to the task. Thanks for the input so far. dhjgreen, OL4 would not be too far. I might come back to you, thanks for the offer.

Pete, thanks for the confidence in the chip. I'm pretty sure it's a simple wrong polarity connection on the motor from what I now understand. I am reasonably comfortable opening it up and potentially swapping the wires over to the motor but if there are any members in our around East Manchester M34 then I'd be very grateful for any offers of a simple reprogramme...

Hi Nigel, I should have mentioned that I've followed the instructions in the manual to change the default direction and all that happens is that both selected directions on the controller make the loco go backwards. I don't know if this is a peculiarity with the installed DCC chip but it certainly didn't do what I expected it to do. Looking into a more manual way to rectify the problem is the cheapest option just to swap the wires to the motor?

Hi, I'm starting to do a bit of DCC modelling with / for my four-year old son. Because he's so young I elected to go for an EZ Command controller which has been fine for the limited amount I've used it. Long story short I've just got our Hornby 00 Thomas R9287 installed with an R8249 chip (not my choice, I'm sure some people will say that was a bad idea but here we are...). Now I've got the loco back I've found that it travels in the wrong direction so need to modify CV 29. Simple enough except for the fact that (as I'm sure you all know) the EZ Command can't read / write CV's. So, as per the title, what would be the cheapest way at this point to read / write CV's to the chip? I have a Raspberry Pi 3 doing nothing at the moment so could a SPROG II be a potential option. I'm a computer tech by trade so am very comfortable with computers if that's an easy option. Any ideas welcome, please don't waste your time telling me what I could have done better before getting to this stage. We're on a budget at the moment due to moving house and second child etc, etc. I was advised to get an NCE PowerCAB when starting onto DCC which would have been the perfect solution for the future but as the controller is also for my 4-year-old this wasn't a sensible option (until this problem cropped up). Help...
