HI everyone,
I have an old lgb track cleaning loco which is fitted with a LGB 555021 decoder this loco has worked fine for many years but now all of a sudden has started having problems as listed below, I run Massoth and as I said I have not altered anything and it is just this loco.
1 If I increase forward speed past speed step 6 loco runs then stops then starts up runs then stops and so on. If 1 run it under speed step 6 no problems with or without cleaning wheels running. If I run it in reverse no problem at all. It is not a power pick up problem as I have a trailing unit which has 4 lgb pick up wheels providing power to the loco as well as found that helped getting this loco over points and crossovers.
2 Cleaning wheel motor is all free and lubricated and new discs fitted to avoid any problems but motor runs fine for 5 mins at full revs then slowly gets slower. I have removed it and run it straight of a power supply and no problems so it has to be on the decoder or the internal pcb.
3 There is a set of micro switches on the pcb and a large 3 way switch does anyone know what these do and what are the correct positions for these when used for dcc operation
Any thoughts or what this maybe or how to solve it would be greatly apricated
Many Thanks
Adam
