Katana Owners Club U.K.

My 1982 Katana. 1100 keeps blowing the main 15A fuse. Do you think this could be overchargi g by the alternator or more likely a rectifier problem,its only just started doing this. Thanks.

i personally would start by getting all the bodywork off and checking all the earths and the possibility of trapped wires....

Have a good look at the fuse box, stick a multimeter across the batt when running

Hi I had the same thing.

It turn out to be the fuse box.

I took mine apart and cleaned the contacts inside.

Thanks for all the help. Turned out it was the rectifier,hopefully sorted now.
