Hi Capt,

Do you try the loco on the prog track first before going to main track with loco

As a readback on programme track can tell you if theres a short before you let the decoder have the power carried on the main track .

I see pounds saving with the next answer

Cpt Jack

What control do you use capt ? as even a seperate piece of track if it is recieving the full track power will not protect the same way as for example a powercab where the programme track can be selected with the cab so to protect the decoder recieving the full voltage initially.

Hi Capt,
Glad you got things sorted out, insulate where the wires route is a good policy at times just to be sure

in time wires could rub and create a short, where any motor contact has touched the chassis a liner of 10 thou plasticard as has been said is better than tape as a sharp solder joint may pierce the tape .... been there done that one

for the programme track instead of plugs you could wire in a DPDT switch as here in the diagram all you need to remember then is the swiych is set to programme track when testing after an install ..... or use a 'switch it' device as Richard showed us

A note about any drilling or filing of the chassis ............. make sure before reassembly any filings have been cleaned off the chassis completley, i wash the chassis in lighter fluid which also acts as a degreaser for any trace elements of grease which can of course cause problems.

John at Bromsgrove will replace TCS decoders provided the buyer purchases the item from him and pays return postage costs.

Success, I have the loco running happily on DCC.

Well a couple of small funnies.

The chip was not defaulted to 03, but 07, which seemed as I thought I had trashed yet another chip, convinced I had not as I had checked with a multi meter for some reason I started scrolling through the addresses and when I got to 07 it set off down the track.

The only other thing is it goes the wrong way to the selected direction, I really don't want to strip it down so I believe I can swap it in the CV functions

Can anyone guide me how to do that on a Hornby elite.

Thanks
Cpt Jack

If you can change cv's capt change CV 29 give it a value of 1 should solve it does for me let me know how you go on.
Page 35 of the manual i have online here far as i can tell .

With most 2 digit Addresses Cv29 will be 6 to change direction make it = 7

Regards Zmil

My mistake Zmil thanks sorry capt if i informed you wrongly, i had it clear in my mind but typed it in wrong what comes of being nattered to while trying to help you here, i shall be having words with them ........
