Fuse blows - apriliaforum Aug 27, 2010If you just put the Indicator wires together the fuse will blow because theres no resistance, this will also happen if one of the indicator wires touches the frame or something. RS50 has only one fuse, so wen it blows everything powered by the battery will no longer work. Fuse should be rated at 7 but you can use a max of 10A safely.
