Spent most of the day setting up and installing 6 MD mXion PWD DCC lighting decoders for LGB passenger wagons. These are a relatively straight forward and easy install in the LGB passenger wagons tackled so far. All were similar to the 31521. The decoder replaces the original LGB 5V regulating board using the existing mounting holes. The only conversion that I initially bodged was my Gourmino, 30520. This dining wagon has one set of incandescents in the roof. The table lights are two sets of LEDs. One set for the tables on each side of the diner. I discovered the table lamps were LEDs upon disassembling the wagon's interior fittings
to find why the tables on one side were not illuminating. Of course Murphy's fifty-fifty ninety corollary had got me. (For those not familiar with this corollary to Murphy's Law, it states that if you have a 50% chance of getting something right, you'll be wrong 90% of the time.) I had cut the plugs off the two sets of leads thinking the table lamps were incandescents. When I soldered the leads together I had the pluses and minuses crossed. In any case, once that was corrected I now have independent control of the dining car's cabin lighting and table lamps thanks to the PWD's two function outputs.
Tomorrow I'll be attacking my other diner, a LGB 3068. This one DOES have incandescent table lamps. I'll finally get around to replacing one that has brunt out as long as I'm working on it.
This is my first experience with MD mXion decoders. These were fairly inexpensive at around $25 each when shipping is included. I bought 10 of them. I'll let the group know what I think of them once they've run a bit.
