Decoders lose their programming

1693 Views 5 Replies 5 Participants Last post by  Richard Johnson
Hi,
I have a Lenz Set 100 with a mix of basic Lenz and Hornby (R8249) loco decoders.
If I accidently create a short circuit, eg putting a loco on the track, all decoders default to address 3.
Is this normal? It is a pain having to re program the locos!
I now know to switch off track power when placing a loco - I am just curious as to how data is actually stored in the decoders.
Can anyone offer some info on this?

Perhaps another reason not to use them. I never had any success with any Hornby decoder on my Lenz system (I have the same system that you have). I now use the Bachmann (ESU) decoders on most of my new locos. Cheap, reliable and very configurable.
