Hi Nico, thanks for the thread I have really enjoyed your enthusiasm, humor and fantastic positive messages during your journey. LOL you make it seem so easy! I'm still baffled as to the cause for my Top Score's not completing the start upseqence, it's not kicking the ball out at game start but your directions all are pointing to the AX relay so I an going to try biasing the switches as you describe and introduce the contacts to my new '443' brush
For the Canadians out there that are looking for some dremel 443's brushes, if you order online from Home Hardware you can get them delivered for free to your local store. Part # 1280581 with taxes $12.42 for a two pack
