Heated grips .. should be around 40 watts .. say 4 Amps .. bit more before they warm up.
If you blow a fuse (rather than the fuse getting old and just breaking .. look at it to see if it has burnt ends) then something caused it to blow .. you need to find the cause rather than just replace the fuse (should not use a larger one - that could cause a fire!) wire a headlamp globe in place of the fuse ... one filament = 60 watts - 5 amps .. two filaments (both hi and low beam) = 10 amps .. this way if the fault occurs the lamp will light up .. and limit the current - telling you the fault has just occurred again .. handy to experiment with .. pull and prod until the globe lights to find the fault. Of course this did not work at home for me - so I wired the globe up to the handle bars and went riding ... only happened when braking hard .. rear brake switch wires had rubbed through on the swing arm .. but only shorted when the suspension was unloaded (braking) and the brakes were applied .. two things needed to blow the fuse ..
