Hello.
I received a loco no. 3331. Unfortunately it doesn't go on my layout. It is an analogue M track with white transformer. Only lights are working. They change directions. A little buzzing can be heard from the engine but it is tiny.

Can I try en engine by putting a power straight on it? If yes, where?
Many thanks

Hello, prior to that make sure to clean the motor of any residue and check the carbons, when cleaning also check that all axles move freely.

Hi,

The decoder of this loco does not recognize the operation mode. For analogue operation all four dip - switches must be set to "OFF".

Hello Markus.
Are you sure? This is not what it says on a box. Also on a decoder there is no switches. See picture above.box.jpg

There are no DIP switches.
Old Delta decoders without DIP switches recognise the operating mode automatically.
Later Delta decoders avoided license fees and required manual adjustment for analogue/digital mode.
The latest Delta decoders hat automatic detection again.

Sometimes 30+ decoders are simply dead.
But Märklin locos out of boxes with a blue line are candidates for hardened oil syndrome (HOS), so maybe the decoder is not dead.
But since the decoder has no overload detection, trying too long on a loco with HOS could kill the decoder.

One more question. Can I put a power on engine to check is it actually working.

You can safely apply power to the motor after disconnecting the decoder from the motor.
Applying power to the motor while the decoder is connected might damage the decoder.

Ok. Where do I apply power to? On a picture above there are 3 cables: blue, green, black. Transformer has only two.

**After deconnecting the decoder ** , Apply power to the black wire side and alternatively to the green side (forward) or the blue side (reverse)
Good luck

Given the period when this model was made, my guess would be hardened oil. You reported that the lights changeover with reverse direction and there is a little buzzing from the motor.
If you remove the core of the motor, you will be able to determine if it is the motor itself or the gears which are gummed up.

I'm hoping it is just this. Not a decoder. Actually I think that loco was never used in a past.

In that case, there is a 99.9% certainty that the mechanism is locked.Wink Wink
Don't bother doing anything before ** unlocking the mechanism**.
It's simple: get yourslef a flask of lighter fluid (e.g. ZIPPO) and pour a few drops in the motor bearings and from the bottom on the gear train.
Repeat a couple of times, let it dry thoroughly.
Remove the brushes and try to turn the (geared) wheels with your finger. If they still appear locked, repeat the lighter fluid routine until it's running smoothly, albeit with a little resistance due to the gear train.
A few drops of oil in the gears, and a very small one on each side of the motor, re-install teh brushes and their springs, and you should be good to go.
Good luck

3331 srodek 1.JPGHehey. I'm proudly to announce it works!!
Engine wheels where stuck. Also another axle was hardly spining. I cleaned engine, put few drops of oil here and there and it flies!!
Only one thing. On a picture electornic in red circle is disconnected from the engine. I mean it is connected but only by touch. I'm expecting new soldering iron so I couldn't solder it? What is it for?
Thanks

Good job.
Don't worry about that component ! It's a small capacitor that was fitted as an interference suppressor.
In the days of cable or satellite TV, WiFi and digital TV and radio they are no longer really needed.
Enjoy the lok!
Cheers
