I am having an electrical problem with my 1999 cbr 600 f4. i need to follow wires from the lower ignition to the ignition control and also check all the ground around the whole bike. so if someone could help me find these ground i would really appreciate. Thanks

 

Download the factory service manual...links are here in the section. Then, use the wiring diagrams provided.

 

The grounds are under the petrol tank.
