Ok, so my new to me 04 DRZ400s is giving me issues today. I was supposed to go on a ride tomorrow, so I went out the start it up and check oil and the usuals. Ran it on the stands for 4 min, shut it off at the key, checked oil it was good. Turn key, start bike...click. Nothing, battery's dead. Strikes me as odd, but ok. So I put it on the quick charge for an hour, bring it back out, starts up first try. Shut it off, hit the start again, click. I know that the quick charge is no where near as good as the trickle charge but i just wanted to check it. So I charge again, bring it out, start it, and as soon as it starts disconnect the battery. Keeps running...it should, but lights go out. So my question is, shouldn't they stay on if the gen is working ok, or does disconnecting the battery kill the electrical loop? Tomorrow morning I'll be starting Nobel's Electrical trouble shooting checklist, but just wanted to bounce some ideas off some of you guys. My other concern is that a couple of weeks ago I pulled off the left side cover and there was a good amount of oil in it, maybe even 1/4 of a quart. Is this something that could damage the generator? I mean there's not acually a spark in a generator it's just an induced voltage in the windings so I wouldn't think it would matter, but I may be horribly wrong here. I did go ahead and drain it all out and change the oil, and haven't found any more in there. So that's my rant... any ideas?
