My son has an 05 z400 and a few days after riding it, there is no power when you turn the key on. I have checked/replaced the battery, checked replaced the main 20amp fuse near the starter relay. I disconnected the ingnition switch and it tests out, I have continuity to the other side of the 20 amp fuse. I jumped the starter + / - and the starter engaged. The manual shows a 10amp fuse near the rediator fan, I couldn't find it but found it hard to believe that this is shutting down the whole machine.

any thoughts would be greatly appreciated.
