Piko motor block wiring

[fridge]

Help, please! I have just acquired an old-style Piko 4-wheel motor block. It has four terminals labelled M1, M2, S1 and S2. I assume that M is for motor and that S might be for skates. Can anyone tell me definitely what they are for? Grateful for any assistance.

Yes, M is for motor, S is for 'schiene' (= German for 'track').

Can't tell you definitively, but I'd strongly suspect that the "S" stands for "Strom", or power..... so the S terminals are from track power and the M terminals to the motor. If you want to be absolutely 100% certain, put a multimeter on "resistance" setting between the wheels/skates and one of the S terminals - if you've got a circuit, then you've got your answer.....

Edit: Willem posted as I was typing..... I was correct, just my guess at the German being a bit off....

Thank you very much, chaps. Now, what can I do with this, I wonder? A County Donegal "Phoenix" tractor in 15mm, perhaps?

I'm not sure if this would be the best place to ask this but can these PIKO motor blocks be fitted for digital control? You see I have one which I want to fit an LGB MTS decoder in but wasn't sure if they are compatible for digital or not.

Yes, easy. The block is already "DCC friendly" as the pickups are NOT internally wired directly to the motor.

Just the block's S terminals to the power input wires on the decoder (LGB brown and white wires, NMRA red and black wires), and connect the M terminals to the decoder motor outputs (LGB yellow and green wires, NMRA orange and grey wires).

Thats great, thanks.
