I have had my 2004 wr450 for about 4 months now. When I first got it the battery was dead so I charged it and it worked great after that, and I have only had to charge it that one time. I went riding monday and the electric start worked fine, but yesterday I went to start it and it acted like it had a dead battery as it just clicked and also my horn and signals wouldn't work. I figured I needed to charge it again so I plugged in my battery tender but it went straight to a green light indicating the battery was charged. My question is does this mean my battery is toast, or could there be something else going on? A dead battery is the most simple obvious explanation, but it seems weird to me it died so fast even though I didn't leave anything turned on and weird that my battery tender doesn't show red when I hook it up but green. Any suggestions would be appreciated, I am going to get a volt meter from my dad's and check the battery later this evening.
