I would contact Jacques Vuyes or JeanJeanB through the forum. You can also submit your question to Rick Sinclar at digital(at)Marklin.com

Hello,

I did such a conversion recently, on my 37591 dated from 1997.

If you keep the Original LEDs, then YES you MUST set resistors on LEDs. 1.2K is a good value.

See my attached PDF, for various schemas, before and after conversion. 37591.pdf (132kb) downloaded 29 time(s).
I first did a conversion with the original LED set, and put 1.5K and 1.2K on each LED set (Front light, rear light, aux1 and aux2). It was working fine.

I decided later to change the original LED set with a LUESSI 8088 couple of LED boards. See there: https://luessi.ch/eshop/..._263&product_id=2437 . It provides additional red led, and had also the resistors embedded. For red led, I've used AUX3 and AUX4.

ESU has a sound project available for this loco: see this page https://projects.esu.eu/...amp;country=ch&cat=7
Note: you need an ESU Lokprogramer to manage the sound project and load it into the LS5.

I have a question with the installation of the Luessi 8088 Ae 8/14 light boards with their 8055 Ae 8/14 decoder adapter board.

I have the 8088 installed plus the 8055 and all works great - headlights plus the white Swiss lights and sound. The question is how do I map the ability switch to use the red Swiss light instead of the white Swiss lights at the rear side of the locomotive.

Per Luessi instructions I have the the front Swiss light connected to Aux 1 and the front red Swiss light connected to Aux 2. For the rear Swiss light I have it connected to Aux 3 and the Swiss red rear light connected to Aux 4. These connections are on the front and rear ends of the 8055 circuit board - Aux 1 and 2 at the front and Aux 3 and 4 at the rear.

Aux 1 and Aux 3 are mapped to come on with F0 forward and F0 reverse lighting, which as I mentioned is working correctly.

Just not sure how to map the ability to switch from the Swiss white rear light to the Swiss red rear light.

Also how to map out the A-lighting for all three white lights on at both ends of the locomotive at the same time.

Can anyone please provide some assistance for programing the ESU LokSound 5 decoder, I am still learning how to do this but with very little actual experience?

Hi all,

This reminds me my own Luessi conversion is not complete, from this thread: https://www.marklin-user...-Ae-8-14---PC-Board-Part


Fabrice- if I read your reply correctly, I cannot use the factory LEDs with the Luessi board, unless I add resistors? Or you mean without a Luessi board you need them?

That might explain my conundrum, hence asking.

Thanks!
