Hey all, I bought a z400 that needed a lot of work. So far I have replaced the frame and swing arm, and all new bearings for swing arm and assembly. I have also replaced the wiring harness as the old one was a hot mess. Now that I have the bike back together, I have no power to the starter. The bike has power as the dash lights come on. I suspected that the starter solenoid was bad so i replaced and still no power .If I jump the solenoid the bike will turn over. Fuse is new as well. I'm stumped. The bike Rand great before I tore it down. Any help is appreciated .

 

Check the negative wire to solenoid, and the thin pos which comes from the start button. I don't know the 400Z, but most Suzukis have an extremely complex lock-out system so it will only start in neutral, could be that not wired right.

 

The ground is good. I will have check out the start button wires again .Bike is in neutral. The green light is lit plus the foot lever is in neutral position. By pos I'm assuming you mean piece of s@$&
