Trainman1974 Posted November 16, 2018 Share Posted November 16, 2018 Can someone help me, I’ve got a Hornby Class 60 TTS sound chip and I reset it back to default setting via the Hornby elink but now my directional headlights currently now stay on even when you press f0 to switch them of only one end goes off but the other end stays on even when you change direction, Link to comment Share on other sites More sharing options...
96RAF Posted November 16, 2018 Share Posted November 16, 2018 There is an isolation switch under the loco - see item 4 on SS286. Its use is described in the maintenance sheet that came with your loco. /media/tinymce_upload/921d61569df177e058280b195fd72b21.PNG Does this happen f you physically turn the loco round on track to face the other way.Rob Link to comment Share on other sites More sharing options...

96RAF Posted November 19, 2018 Share Posted November 19, 2018 If you cut the plug off and soldered it into the Lima loco yourself, chances are the wiring is wrong or your loco has opposite polarity lighting. DCC decoders are rigged for positive anode leds.Rob Link to comment Share on other sites More sharing options...
Trainman1974 Posted November 19, 2018 Author Share Posted November 19, 2018 Ive got the decoder plugged into a harness which is wired up to the lighting and the motor, if I take the sound decoder out and just plug in a non sound decoder the directional LED lights work normally, could there be a problem with the sound decoder as I did reset the decoder via elink by writing 8 to cv 8 could that of resetted the lighting function.

Fishmanoz Posted November 19, 2018 Share Posted November 19, 2018 Resetting a decoder means the default values are written to the adjustable CVs in the decoder. There are no adjustable CVs associated directly with lighting, so nothing has been reset there. However, for directional lighting to operate, the decoder must be set to 128 speed steps in CV29. So check the value of CV29 to ensure it’s default value has been correctly set to enable 128 speed steps. Link to comment Share on other sites More sharing options...
Trainman1974 Posted November 20, 2018 Author Share Posted November 20, 2018 Yes CV29 is set to 6 and it still doesn’t do anything, but like I said I can put other decoders into the loco and they work fine, so I’m wondering is it the decoder itself which has become faulty in some way.

96RAF Posted November 20, 2018 Share Posted November 20, 2018 TTS decoders have a fairly low current limit on their function outputs 100mA. Is your lighting load within this limit. It may be your other decoder can handle it but the TTS one can’t. I fitted an Express Models led kit to a Class 37 and the sum current of 2 x reds, 2 x markers and a hi-power headlight was outwith the decoder limit and I had to tame it with an extra resistor in the blue wire. This overload showed as odd lighting effects and eventually the decoder seemed totally duff., but luckily after controlling the lighting current it recovered. If all fails then invoke the TTS Warranty which now covers accidental damage.https://www.hornby.com/uk-en/media/Fitting_a_Decoder.pdf Link to comment Share on other sites More sharing options...
