To make a short story long, I've been running G-scale trains on my brother's layout (Lone Pine and Western Railroad) for a few years, every time he needs some help to show it off (yearly open house). Then I got a wild idea and decided it would be nice to have my own engine (his stuff is all narrow guage). So, I bid on and won an LGB 20892 (Sumpter Valley Mallet). Since my brother's layout is dead rail it will be necessary for me to convert the locomotive to battery and remote control. My first challenge was finding information on the 20892. I got the manuals and 'exploded' parts displays, but getting the thing apart was quite a challenge. That is when I found your web site/forum and found the information I was looking for on disassembly. The locomotive was manufactured in 1994 and is DCC ready, according to the Massoth web site (based on the sticker on the bottom). So I planned to use a Massoth eMOTION XL decoder, and for RC I was planning on using a receiver and hand controller from CVP Products (specifically the CONVRTR-60 receiver and T5000 wireless throttle), along with one of their 6.8 Ah lithium ion batteries. Now comes the fun part. I believe that all I have to do is connect the decoder to the existing PCB, using Massoth's 6 conductor cable, and then cut the two sets of white/brown wires that bring the power from the wheel pickups, and substitute power from the battery, via the CVP receiver. Sounds simple enough(?). One question I have has to do with two sets of wires that come from the rear drive unit to second PCB. One set has three black conductors, and the other has two black and one brown conductor. I was wondering what function they serve, if anyone knows. I have been unable to find any specific documentation on that. Any and all comments/suggestions will be appreciated.
