So I got really close to firing up my neat little chop. I extended it 4 inches, solo seat, Honda 125cc gas tank, Harley headlight, the list goes on. However, I always scoff when I read "disconnect battery". I have always thought "well what can happen?". I found out you can fry one of the capacitors on your TCI. When working on some things it is better to remove the battery to have it out of the way. So if someone would please send a picture I would be so happy. I cant seem to find a picture on Ebay. The prefix is 3Y6. The board number is HSA-04 C. I know it is a sealed unit but if someone has one open I sure would be thankful and riding happy. Also I will post a picture of the board if necessary.
