hey guys, I've got a question about my SV from 2002. How many ampere does the ignition have? The lights have 15A. I've always had a 10A with my ignition, but a week ago my bike stopped all of a sudden. Now it has a 30A thingy (what's it called in english

) for my ignition. How come it just happened a week ago that my bike stopped and not earlier? I've been driving for about a half a year with my bike, so?

I don't think I understand the question, but the thingy is called a fuse

A fuse has a finite life, meaning that the more it is used the weaker it becomes. Therefore although the ignition fuse is designed to blow at 30Amp that includes a safety factor, theactual ignition current is probably very much less. Eventually the value at which the fuse blows will fall to that of the ignition current, at which point the fuse blows. Don't worry unless the ignition fuse keeps blowing, then you have a problem. This problem is usually water ingress, or damage to wiring insulation, recently I managed to get water into the fuse box, this caused the ignition fuse to blow when leant over on roundabouts. Not a particularly safe place for the bike to coast to a halt!

oh thank you, a fuse! oke. My question is what fuse is there normaly is with the ignition, in the box on top of my battery. I hope I'm making myself more clear now

I'm fairly sure it should be a 30Amp fuse, but I think it also tells you, either on the fuse cover or in the fuse box itself.

Hi Sam
the thing to check with a bike of that age is where there are known problems with the wiring being damaged which can make the fuses fail.

The places to check are where the 2 bolts holding the rider's seat go through the frame brackets. The wiring is right behind the brackets and the bolts are a little too long, so can touch the wiring.

The other place is under the passenger seat, and look on the left side of the bike where the wiring runs round the edge of a bracket welded on the frame, towards the back.

If there is any damage to the wiring, you can usually repair it with some electrical pvc insulating tape.
