Dear model railway enthusiasts, in this video I show you my first attempt at digitizing the Märklin steam locomotive BR89 with the item number 3000. Since this model is relatively cheap to buy as an analogue steam locomotive, I have attempted my first digitization with the small steam locomotive. There are a few things to consider that I don't want to withhold from you. For this I used the Märklin locomotive decoder mLD3 with the item number 60982 and the high-performance motor retrofit set with the item number 60943. The tools I used were a soldering iron, a magnifying glass and a small grinder, such as a Dremel. You can also get a few new LEDs for lighting the locomotive, but you have to be careful to use a suitable resistor between the LED and the decoder. When digitizing, I start by removing the old motor and the mechanical switch; both elements are removed from the chassis of the vehicle. The new high-performance motor retrofit kit from Märklin 60943 is then installed. This fits very well, but the lower fastening screw of the motor plate must be carefully sanded down with a Dremel so that the screw does not rub against the wheel of the locomotive. When connecting and soldering the decoder connections to the motor and the lighting, make sure that the correct cables are connected to the motor plate, as well as to the lighting and ground of the locomotive. There are differences in the cable colors between the so-called NEM standards and the colors of the pure Märklin decoders. The instructions and correct assignment can be found in the enclosed instructions. The additional installation of digital spotlights on the model locomotive and possibly rear lighting could be a bit complicated, as additional series resistors must be installed between the decoder and the LEDs. The strength of the series resistor depends on the voltage of the LED.
