Hello again, yes you've guessed it i'm in trouble again,
I purchsed a lovely Terrier today and have fitted it with a Hornby chip as per the instructions supplied in the PECO manuel for installing decoders. No probles=ms there the chip went in easy and it's running ok. The problem is the noise, when it's idle no noise, but running even at low speed it makes a racket, the more speed applied the greater the volome. Is this normal with this type of loco or have I done something wrong? I took the capacitor out when I fitted the chip, would reinstalling it help?
Thanks for your advice,
Mike

Thanks for the help everyone, the noice is motor not mechanical, the loco runs very smoothly no complaints there, it just whines whilst running, the greater the speed the higher the whine. I took the body off and detached the decoder from the motor and this cured the whine, toruble is there's very little room in the body for the decoder to go so it has to fit snug against the motor. As soon as I put the body back on and screwed it together again the whine was back. Any further suggestions?
I will contact Hornby and see what they suggest, sorry not sure what a CV code is or how to change it, don't forget I'm very much DCC for beginners!
Thanks again Mike

Hi sorry I've not replied, PC troubles. I don't think the decoder is causing the motor to press against the casing, but the idea of moving the decoder to the coal bunker is appealing. Yes I'm using Hornby decoders.
I've tried putting pictures on here before but without success, I followed the instructions in the Peco book, I think it's called "installing locomotive decoders" but I haven't got it to hand to check.
Basically you detach the three wires from the picks ups on the axles, (red, yellow and black wires) from each side of the motor, group the three together and attach the black decoder wire to one set and the red decoder wire to the other. The orange and grey go to the motor terminals as usual.
The instructions place the decoder on the side of the motor, (use double sided tape). I've never placed a decoder so close to the motor before, and as you will appreciate I'm not happy with the result.
I'll look at moving it to the bunker at the weekend.
Thanks again for your help.
Mike
