Guys any assistance would be appreciated. My 600 Thundercat started ok this morning but I switch it off then tried to restart and the neutral light went very faint and it would not start off the button 

after a bit of checking the battery is  ok and fully changed but the fuel pump relay in making a clicking noise. I bump started it but it was spluttering like mad and Rev counter was flying up and down 

any ideas 

How did you test your battery? measuring the voltage across the terminals only tells a small part of the story.
