Hello,
I've got a Wild power unit like this one:

But it seems to have had some modifications in wires output (see pictures)......
Especially a large yellow wire has been cut in top of transformer (see pictures)

If anybody owing this power unit could make pictures of the right original connections, it would be helpful for me

Thank you
