I have a Kawasaki GPZ 400 Ninja. I was riding on the N1 when the bike cut out - all lights on the instrument panel also went out. I pulled to the side, the bike didn't want to start. I checked the fuse box to find the main fuse had blown. I put in the spare fuse, and as soon as I turned the ignition to on, the fuse blew again. obviously this is a electrical issue, some one mentioned it might be the rectifier.

Can some one perhaps give me some advice on what to do / check or what could be the problem. Or direct me to a bike electrision in Northern suburbs area.

Thanks
