Hello girls and guys,

I would like to run my old gauge 1 loco AC on DC.
How can I manage this by using diodes ?
Can anyone describe me how (perhaps with a sketch)??

Kind regards

Soeren

That depends on the type of motor. If it has a permanent magnet for the field it should be easy, if it has a wound field it's still not difficult but slightly more involved. It would also help to know how the reversing was performed with a.c.

A photo of the innards may help.

Hi Soeren, Is this a Marklin MAXI loco?

The plug-in board looks very much like the Delta decoder that came with my MAXI loco, and which I replaced with a DCC decoder.  My loco has a DC motor and also comes with a DC adapter board, Marklin part 66802.  You just need one of these (on the left) I think?

It should be easy to make an adaptor if you can`t find the Marklin part.  The diodes are only there for the directional lights, and the adaptor plate bridges the track pickups to the motor connections.

I made an adaptor board for my DCC decoder from standard copper-strip board, like this:

I found the 66802 on ebay.de:    http://www.ebay.de/itm/Marklin-66802-Spur-1-Gleichstromplatine-2-Stuck-/171664840330?pt=DE_Modellbau_Modelleisenbahnen&hash=item27f805968a
