LGB Mallet 23851 Massoth decoder fitting

Zerogee said:
I've actually just done one of these in the last couple of weeks, with a lot of help and advice from Peter (Whatlep). Mine was actually a 22852 with factory sound, which had been MTS-fitted at the factory with a pretty awful lash-up of a 55020 and a 55030 booster. After finding that the 55030 was almost certainly faulty (not unusual, it seems), I ripped it all out (just the decoders, not the sound board!!) and put in an XL, which works beautifully. Peter has described it very well, though in my case the decoder went into the smokebox as the big sound board takes up most of the main body space. I hope that the attached pic might be of some use to you.
Just to reiterate Peter's warning: MAKE SURE YOU MOVE ALL THE DIP SWITCHES TO "OFF"! In my case, this was the white block of six red switches immediately forward of the eight connector pins for the motor and power leads; the layout of your non-sound main board may differ.

Jon,
The picture you posted is no longer appearing. Could I ask you to repost it? I know its along time ago and will undoubtedly not be easy to find. Thank you.

Hello Jose,

I think you will still have to operate the sound on your Mallets with serial rather than parallel commands - when you run that loco (or program its details into your Navigator and save them) you will have to set the Navi commands to 14 speeds steps and SERIAL control. If it's like mine, all the function buttons should then work as they should with a single push - though there will be a couple of seconds delay while the Navi sends the multiple serial pulses to the loco.

Best,
Jon.

Jon,
By chance do you have that photo to repost because it is no longer appearing? Thanks in advance
