After watching a friends bike go up in flames from a short I did some thinking about the situation. I decided that I wanted some protection from a similar fate and came up with a solution. I put a 50 amp switch in the ground line from the battery to the frame. The logic was that with this arrangement I could kill any short circuit by throwing a single switch rather than having to find the offending wire. Located in a covered location it was also cheap theft insurance. I just switched it off when I parked. In 20 years I had one switch failure, most likely a victim of the "Vibraglide's" rigid engine mounting setting the whole bike into spasms. On the road it was a momentary annoyance to remove the seat, take the switch out of the line and motor on to the auto parts store. Airborne it probably wouldn't be as easy.It seems to have been a valid solution for the Harley but is it good practice otherwise?
