Shedmaster 47 Posted June 2, 2017 Share Posted June 2, 2017 Hi Folks , I recently picked up a second hand bachman class 66 610 in freightliner livery .it has been fitted with a chip and runs very well from a crawl to a sprightly full speed .the strange thing is thought, when I pressed F1 to check if cab lights were fitted ( F7. F8 does nothing ) the main lights noticeably "DIM: press F1 agsin and the return to full brightness!! I am not complaining about this unusual quirk , but would like to know if it's a chip malfunction or if it's meant to do this from a specialist supplier ( homes, olivier's etc) The chip seams to have no markings to tell whos/ what is is !! Can anyone shed any light ?? Many thanks .Allan Link to post Share on other sites More sharing options...

Many thanks .Allan Alan Unless it's a typo - F0 (normally) controls the lighting not F1 Cab lights if fitted ? are normally on a separate F key, which, will depend on whose decoder is fitted, and if it has been re-blown etc... It's also possible that the original lighting wiring may have been altered from standard. Do you have any user instructions for the fitted sound decoder ? Obviously something odd going on with the lights dimming and then going back to full brightness. HTH Ken Link to post Share on other sites More sharing options...
Shedmaster 47 Posted June 2, 2017 Author Share Posted June 2, 2017 Hi Ken ....it's NOT a sound decoder at all.. Upon further looking at the chassis and the decoder it would appear to be a bachman 36-552 ( cos some of the sleave was taped to the chassis !! ) As you say F0 controlls main lights/ rear lights .however i have SOME digital " cab light fitted " locomotives where the cab lights are controlled from F1 !!! ( Normally reserved for engine startup with sound equipped loco ) This machine however does NOT have cab lights ..... F1 does seem to make the lights dim however and pressing again returns to normal brightness !! Strange !!!....... Link to post Share on other sites More sharing options...
SRman Posted June 3, 2017 Share Posted June 3, 2017 (edited) I am not very au fait with American practice, but many of their locomotives have a dimming function for the lights when certain other functions are selected. I wonder f that may be the case with your 66 decoder, in which case it is nothing to be alarmed about; just a curiosity, as you said.

It is fairly simple to program the 36-552 to dim lights by pressing a particular button (eg. F1). So, I'd guess that is what the installer did when installing the decoder. If not liked, then its fairly simple to change it or turn it off. Bachmann manual is at http://www.Bachmann.co.uk/pdfs/36-552.pdf Link to post Share on other sites More sharing options...
Shedmaster 47 Posted June 3, 2017 Author Share Posted June 3, 2017 Thanks gents , I will download the bachman PDF manual for that chip and then take a look .... Link to post Share on other sites More sharing options...
Shedmaster 47 Posted June 3, 2017 Author Share Posted June 3, 2017 Hi Nigelclife Ave downloaded the PDF for the chip but it doesn't give any specific instructions as to how to program an "F" button to do a certain task !! Just that CV 64 controlls the brightness of certain lights when once programmed to dim them !!! I use a Prodigy express system , I wonder if I could be a pain and ask that you " walk me through " the nessessery process?? As it might just be useful to set other loco to have this feature!! Many thanks ..Allan Link to post Share on other sites More sharing options...
Shedmaster 47 Posted June 3, 2017 Author Share Posted June 3, 2017 Correction CV 51 sets the "F" button and CV 52 controlls the brightness it says ... My loco seams to have had "F1" programmed to DIM the lights ... I am assuming I just alter CV 52 to adjust OR CV51 to disable it altogether ?? ...

Nigelcliffe Posted June 3, 2017 Share Posted June 3, 2017 CV51 sets which function key is the "dimming" switch, or a value of 0 means "constant lighting level". It would appear to be a bit-switch, thus 1=F1, 2=F2, 4=F4, 8=F4, etc.. CV52 sets the dimming level, from 0 (dark) to 255 (full brightness, no dimming).
