Ed hi,

I'm not sure but from your description I understand that your model is a Delta digital one (motor with coil). If the motor is a 5 pole one, then it might give you somewhat better driving characteristic to replace the coil with a magnet and add an ESU. If it is not, putting in a 5 pole in will definetely improve the running.

ESU decoder + magnet option cost almost like M*.

Ed, If it is definitely a 3602, then it has a 3 pole DCM motor, with 6080 decoder, which is the earliest type made by marklin and has no load regulation.

The cheapest way to make it high efficiency digital is with the 60760 decoder kit. This has the parts for the 3 pole to 5 pole conversion, and a reasonably good, load regulated decoder.

Next most expensive is with a Hamo magnet and ESU decoder, as you suggested, and will give you similar performance but not quite as smooth at low speeds because of the 3 pole motor.

Best conversion, but at a price, is with the 60921 decoder kit. This is like the 60760 but with a better decoder.

Alternatively, you can always mix and match and substitute an ESU decoder in the marklin kits. Some prefer to do this.

EDIT-

PS - Are you sure it's the decoder. You can also sometimes find 6080 decoders for sale on Ebay very cheap. Try just replacing it to be sure, but also follow Sander's advice and check the motor and brushes first.

Good, they are my staple for all DCM conversions.

Hello all,

Thanks for all replies in special to RayPayas.

The model is 3602 and I am almost positive that has a 3 pole rotor, although the owner's manual mention includes instructions for 3502 too which is high efficiency 5 pole and non dig (?). So the 3502 would ride better than 3602? Is another M* non-sense.

The model is in new mint condition. I remember now that I tried to run it 6 years on some tracks that laid in my place with a 6021 and didn't worked. When I took to the Marklin service guy here in the Bay Area, it was running with an intellibox. I stored again. Recently, I took out of box and it is not working again [:(!] .

There is not hum or any indication that the motor wants to start. First, I will check the brushes.

Is the 60760 decoder kit a decoder plus 5 pole rotor plus a permanent magnet like the 60921 decoder kit? Because if is the case, it is 3 times cheaper [:0] than the later one. What would be the riding differences?

Can I get just a 5 pole rotor and magnet kit from M*? What is the part number?

Thanks again,

Ed

The only difference AFAIK between the 60760 and the 60921 is the decoder. The running is not quite as good, but acceptable, and there are no functions apart from lights and f4 for disabling the acceleration and deceleration delay.

If you want to get the motor "bits" seperately, you will need:

386820 anchor
389000 field magnet
386940 motor shield
516520 inductor
601460 pair of brushes
