Hi Guys, I think this topic has been covered before but maybe some one can give me the abbreviated version on how to fix this problem of mine. I have just installed a Lokpilot v3.0 M4 (21 pin) into this loco & I am trying to use the old 62255 Swiss lighting changeover board with not much success. Installed as per http://www.jus-kn.de/ch_licht.htm using 3760 digital diagram. When I get it onto the programmer it takes a long while for the lights to come on & when they do they are very dim. If I switch the lights off & on there is nothing for a long while till loco moves. If I transfer loco to my layout using Ecos 50200 then lights will not operate period. In the below not so good pictures the two yellow outlet cables to front & rear are bridged to get the two on in front & one right rear to operate. If I remove this bridge the front & rear lights operate directional on both controllers but rear single light will not come on. Something in the bridging causes the whole issue. Now I believe I can throw out the whole 62255 board altogether & just use the Aux 1 & Aux 2 outlets. Not to sure how that works but I am told to change the CV141 value 5 & CV144 to value 6. How do I change a CV on a M4 decoder when you cannot access it on the programmer. So I either fix option 1 or throw it all out & use option 2. Any ideas on this with photos would be much appreciated.

Hi!
There is one important difference: the 60760 indicates overload by letting magic smoke out while recent ESU decoders just leave the lights off.

When function outputs are dimmed, they still provide the full voltage - but only for a reduced percentage of time. This reduces the average wattage flowing through the lamps, but not the peak current (which is still too much for the decoder).

Good to hear you got it sorted without any damages.

Dave,

I'm surprised you got it going at all because the lightchange board is made for analog locos and not digital.
