My bike was running fine on a dual sport ride this past weekend but then about half way through I had no battery power. I could bump start the bike but that was it. I got it home and pulled all the leads from the battery and put a battery tender on it. The tender ran for a bit and said it was charged. I put the leads back on and turned the key and nothing. No lights, no starter, nothin. So i am digging around and looking at all the fuses and connections and I dont see any problems. So I decide it must be that the battery is bad and the battery tender is lying. Wrong! I decide to run some jumper cables from my other bike that has a great battery. I hook up the cables and turn the key on the KLX and nothing! I unhook the cables and turn the key on the VERSYS. Now the Versys battery is almost completley dead. WTF. this was all of 3 minutes and it completley drained the battery. I am at a loss. What kind of a short or part going bad would drain a battery that quick? Is it the rectifyer? Something else? I am hoping someone can help me. I am not very virsed in motorcycle / car electrical systems other then the basics. I have a multi meter but may need detailed instruction if you want me to use it to test something. I usualy just use it for continuity tests. 06 KLX250S. I have put the 351 kit and pumper carb on it. I am ok with the mechanical stuff but really need to get better at electrical.
