Barra, enough. I've not claimed to know anything about anything except how the electrical system on the WR works and again, I'm right. Backtrack, talk circles, come up with whatever excuse you want but you are still wrong. I told you to try it, you didn't and are proved wrong. As well, Trail Tech stator or stock the OP's question is WILL THE BIKE RUN WITHOUT A BATTERY; the answer: no. Nothing about lights, AC or DC or anything else was asked, your reading comprehension is severely lacking, sorry to say and you long rant still talking about it completely off the topic at hand. Again, try your own advice, an 03+ won't start without something in the circuit. A battery is the best thing, but a properly sized cap will work as well. I've not explained the charging system because I shouldn't have to and refuse to stoop to your level and badgering. So I've not explained it wrong, I've just not explained it to you, so again you're wrong. Your "magic smurf" weird third person explanation above proves just how much you know. Or how little. And I only mentioned my electronics background once in all my posts on here in hopes you'll start to realize you may not know what you think you do and stop, I guess not. I've informed the mods before of his wrong advice; not poor, not mistaken, but flat out wrong information that can cost people broken equipment and so far they've done nothing so I wanted to not have you have you suffer fools advice and needlessly get frustrated and maybe blow money on things not broken. Mike Blablabla see edited post above .. As for your ''telling the mods and them not doing anything''... Maybe they know you are FOS too.
