Modification of a Märklin BR 89.0 - 30000 locomotive.

Recently I modified a Märklin 30000 locomotive, fitted it with LED lighting, 3 white LEDs and 2 red LEDs, both at the front and rear.
The driver's cab is illuminated with 3 white SMD LEDs and also 2 orange LEDs for the smoke box simulation effect are built in.

The modification itself is not expensive because I use the existing decoder in this locomotive. This has the inscription: KN160725A on the rear.

This type of MFX / DCC decoder is built into these 30000 locomotives by Märklin from around 2017.

All adjustments of the necessary CV values, as I have done myself, can be carried out with a simple Märklin MS2.

For this 30000 modification, check out this Dutch website, where everything is described in detail. Hint: Use auto website translation.

A detailed conversion description pdf in English can also be downloaded from this site.
