I have an older 3102 BR 53 0001 fitted with a basic 6090 decoder and upgraded motor. Today when I checked her out I found that the lights and dual smoke units were not working. I am using a 6646 transformer.

The light bulbs and smoke units are OK, but I cannot see where the power for these is fed from. The wire runs under the motor and disappears. Is it safe to assume that the power is fed directly from the center rail pickup?

Before I start tearing out the motor to look underneath to see where the wire starts/ends, perhaps someone would be so kind and tell me if my assumption is correct.

Whilst tracing out the wiring earlier today, I found a whisker of steel wire attached to the magnet along with a short Lagerbolzen (gear axle/pin) part 13 (231840) on the exploded view diagram. Not good I thought...but all of the gearing and gear axles appeared to be present. Someone's sloppy work no doubt.

Today I also had to repair the post that is under the tender top, the one that the holding screw screws into. Someone had overtightened it and broke off the plastic post near the bottom. Consequently the tender top would not stay on. They also botched that repair too, but I made a permanent repair to it, at least the broken off plastic piece was still inside the tender. I have got into the habit of assuming that any plastic that needs to be glued is of a polyolefin type, so I use a primer before using any superglue, liquid or otherwise. Polyolefin plastic used to be a nightmare to repair, but no longer.

Maybe I should go sit out by my pool in the sun, it seems it is not my day for model trains today.

I just made a discovery. My instinct told me to try the loco with one of my MS2s. I did and everything was normal again. Obviously when run on analogue AC the only thing that works is the motor.

At least while I had to bodies off, I took care of some essential maintenance. Digital is still a mystery to me.

Both sites have the info's that may be useful to you

There is more literature available

The 6090 decoder is old. Has only one function: the lights (with flickering).
If you want smoke generator (2 in your case ) you have to connect them directly to the red wire or replace the decoder with a newer one with more functions.

The smoke generators must be 16V-22V.

For two smoke generators is necessary to use a relay or a transistor amplifier to have the required current (something 140 - 180 mA)

Thanks Costas. Good information.

In this post that I did some months ago you will find an easy way to cure light flickering

Is in a more complicated Re 460 Swiss Loco but the principle is the same
