LGB Mallet

[DRG11]

Hello all,

I've put a Massoth XL decoder into a LGB Mallet #22852 as per instructions here but im having problems getting it to work !,

The loco will not respond to #3 on the navigator which seems odd so I've obviously done something wrong, all the loco does is crawl forward making its sounds but it will not stop.
I've checked that all the wires are in the right places including the LGB interface cable wires .. all OK, The dip switches have all been moved over as instructions,
A photo of the attached decoder/wiring is here .....


Any ideas please ? Many thanks to all for any help.

Have you done anything else? - Had the motor-blocks / motors out, at all?

Firstly, I would check that both sets of wheels are rotating in the same direction.

Examine where you have two wires into a decoder connection. - Easy to get a whisker of wire shorting between to connections.

Unplug the 6-way connector, see if it runs..

Unplug each motor-block, and see if it runs with either. - better done on rollers, or blocks.

Was the loco running OK before you attempted to fit the decoder?

Can you read CV1? - What value does it return?

Can you read CV29? - What value does it return?

Report back..

Hi Philip,

I haven't touched the loco except to put the decoder in and was working ok before.

I removed the decoder and know I its got worse as there is a burning smell coming from the loco without the decoder in, the sounds are still there but it smells like burning but I cannot see anything !

cheers

Hm Dip Switches?

 

[PhilP]

Could the burning smell be the smoke unit?

Unplugging the 6-way, the track and motor leads, and returning the DIP switches to 'on', should revert the loco to analogue.

If you have done nothing else, then there is a fault, possibly a stray bit of wire, or something has failed on the original boards.
