There should be two black wires on your TTS decoder if it is the same as a merchant navy one. One is the feed to the loudspeaker, one is the track pickup. If you look halfway along the decoder there should a red and black wire connected, these are the speaker wires. The black track pickup comes from the edge of the board. This is one wire you must not get wrong if it is the track pickup, it has the unique ability of blowing up the decoder if connected wrong. Unless you are happy soldering wires it is a return job.

Colin B Thank you very much for taking the time to reply looks like it is a return as my dsoldering skills are not good to say the very least

Just a picture to illustrate Colins info. The speaker wires are the black and red coming off the right side of the decoder. The pickup and other wires are in that mess at this end.

Good afternoon

I have just purchased a hornby TTs R7146 sound decoder. Unfortunately I cannot seem to get the decoder to work and have noticed that there is a black wire that is loose and not connected.

Please could I have some advice as to wether or nor this wire needs to be connected. The loco runs fine with another non sound decoder when fitted.

All replies graetfully recieved
