OK, I've given up on this project. I have 4 DC05 Motorheads (untested because I've nothing to test them with!) , 1 wand, 1 handle and 2 bodies (both motors dead). There aren't any wires in the hose and neither body seems to have any electrical attachments for the motorhead wiring.
I'm open to offers! Looks like I got stuffed here but it would be nice to get a few pennies back for a mistake if someone could make use of them.
PS. They don't start playing Overkill or Ace of Spades when you plug them in either!!!
