Good Afternoon Everyone

I'm new to Marklin so looking for a little help


I'm fitting my first point motor in my Marklin C track

I'm using a mobile station two but I want to control my points with a 72720

I understand both blue wires go to the box.

Can I use track power to work the point or do I need a separate power source?

Does the yellow wire go the positive wire of the power or negative?

Thank you for any help

Hi
If you wish to control yourpoints "the analogue way" with a 72720 control box, you need a separate 16 VAC power supply
- brown or one pole to the track 0 connection and to the 72720 control box common (on its side)
- yellow or the other 16 VAC pole to the yellow wires of each point's motor.

ATTENTION: Never Ever connect the yellow to the B of track as it will destroy your Mobile station or its track box.
Cheers
Jean
