Riderr Fuse Hub

Arrived very quickly, l installed the unit to my vfr800 , 2 wires clearly + and - the acc wire goes to a power wire that only powers up when the ignition is switched on , l did all this and when l fitted my cable for accessories , the fuses blew when l switched the ignition on ., l opened up the box to find out what the cause was, it appears when I tighten up the screw for my accessories wires they both touched and blew the fuse , I then refitted the wires but with less pressure on the screwdriver , l had to buy some 5 amp fuses low profile, fitted them and tried again ,this time no problems, so my advice is not to tighten down on the screws so to stop turning the holders inside the box from moving and allowing the external wires from touching and blowing the fuse , so reason 4 stars, instead of 5 stars .
