I have 2003 ZX6R Kawasaki ninja and I need help. I bought a brand new battery about 3 months ago and used it a couple of times with it. I let it sit for a while without use because I had to much work and I really could not find time to ride it. Now that I have time, I tried to start it but nothing happen, no lights, no sound, no nothing. "Battery is dead", so I went to my local Wally World and bought a battery charge. I conected but It says that the battery is cfully charged! Could it be the battery, or the bike? I checked the bike's cables and they look alright. Please help.
