Bought a used Ninja 400R (2011 Canadian Model Year. Yes its unique to Canada! Same as 2018 models worldwide)
- 16k on ODO
- Seller said "Bad" battery or Rectifier (SH678A-12)
I first replaced the oil before I did anything.
I replaced the battery with a brand new and it started right up. Rode it very little maybe 10 mins and parked it. Next day rode it up hill just in first gear and parked it. Wont start now.

When i turn the key here is what i see:
- Dash lights come on. "N" shows on the right side in GREEN and "Oil" light turns RED on the left.
- High beams/Low beams DONT come on. Before they did! (I checked the fuse, seems okay but i didnt test with volt meter yet) Maybe they should only come on when engine runs.
- When i press the start button, i can hear a faint buzz near the fusebox. (Seat removed) It only comes for a second and stops. Hard to reproduce. Its almost like crackling/clicking but very very faint. Can be both buzz/crackling.

What i already tried:
- Tried starting with another fully charged battery.
- Tried charging the current battery, still wont start.
- Shorted the starter solenoid, it tries to crank but wont start. Almost as if the engine either doesnt get any voltage/power.
- Tried with the kickstand both up and down.
- Bike is in neutral as it shows on dash

What i didnt try:
- Testing the voltage on both batteries. (One of them is brand new and it ran the bike no issue)
- Testing the clutch safety switch(Did short he wire and it didnt make any difference)
- Testing each fuse in the box
- Testing the rectifier somehow?

Now this may be a walk in the park for some one who knows bike stuff, its my first bike ever. All i can say i hear a very faint buzz very close to the fusebox. Thats it.

Any help?
