I've got to weld a cracked bolt attachment fitting where the baggage support side rail mounts on my 1150R. My question is: Will I have to disconnect the bike's computer to prevent damage when using a heliarc? At least I guess you call the welding gizmo a heliarc. My nephew is a welder and will be doing the work, but he wanted to make sure of the bike's electrics. Obviously I know absolutely nothing about welding. I need help guys!
