Troy, you can easily pick up a new magnet for the crane off ebay.de, just search for märklin hebemagnet.

As I said in your other post, you can use a standard 7072 control panel with the crane. As for the wires, there should be a brown wire, which gets connected to the brown output on the transformer. The yellow output from the transformer goes to the input of the 7072 switch. There should be 5 other wires - 2 red and 2 black and one yellow. I can't remember which is which, but one pair controls the hook raising and lowering, and the other the crane rotation. The yellow wire is for the cabin light and magnet activation. All 5 get connected to the 7072 switch - each pair to a separate bank of red/green buttons. The yellow connects to one of the green outputs on the 7072. Hope this helps.

It works!! The motor for the magnet makes some noise, but it gets better the more I use it. Thanks for your help.

Troy,
Did you email me a week ago regarding the instruction manual?
If so I do apologise, my pc has crashed burnt & died along with my emails, so I am stuck either with the work 'puter or our lap-top.
Please email me again if you still require the manual and I'll see what I can do.

Regards
Tony
