My battery is dead. No bones about it. All tests confirm it, and all attempts to charge it are fruitless. It was old-ish, and not not in the best of shape to begin with, so it's no surprise. What was a surprise though, was the fact that despite the scoot kick starting just fine, the turn signals apparently run directly off of battery voltage, and it has dropped to the point of making them non-functional. All I get is an annoying crunchy 'buzz' when I try to turn them on. Even with the battery charger hooked up in 6A mode and the scoot running, it barely runs the flashers, and they still make a brief crunchy buzz when they click 'on' and 'off'. "Crunchzzz-click! (on) Crunchzzz-click! (off)" What's worse is the low voltage 'partially' engages the flasher, but in so doing completes enough of a circuit that turning the switch off, does not break the 'contact/break' cycle of the flasher, so it continues to buzz. It stops when I turn off the key and/or kill switch (completely de-energise the entire system), and remains 'off' when I restart the engine. Now, I can live without turn signals for a little bit until I work up the funds to get a new battery (I do know my hand signals after all ). What I'm concerned about is whether or not running the scoot in this condition will risk voltage regulator damage the same way running without any battery would. I can't imagine why it would, but then... I'm an automotive gear-head... I'm not as familiar with scooter electrical systems. Thoughts? Opinions?

Sounds like the scooter has an electrical problem and is probably the reason the batter died in the first place. Have you tested the charging voltages?

Running with a dead battery will burn up the R/R which is probably burned up by now and is sending the voltage to ground and will start wiping out some of the electrical. Never run with a dead battery. Alleyoop

Update:
So I did some more noodling around online and discovered the 'sealed' battery isn't quite as sealed as I thought. A little work with a small flathead screwdriver removed the 'seal' plug-strip and I discovered the battery was bone-friggen-dry. I added some water, and popped it on the battery charger at a 6 amp rate for about 20 minutes to (hopefully) blast off any deposits, then dropped it back to 2 amps for a couple of hours.
I couldn't find my multi-meter, so I was unable to take any measurements, but it was merrily bubbling (and quite warm) when I went back to check on it, so it was doing something. I reinstalled the battery, and while it still wont even make the starter 'click', it took at least enough of a charge for the turn signals at least work properly now, which is good enough for my purposes for the nonce.
Unfortunately, as it was running I noticed that there was water (electrolyte) seeping up past the plug-strip. I'm hoping this doesn't mean there's an 'overcharging' issue. I guess tomorrow when there's more light out, I'll head back out and pull the battery again, and dump a touch of the electrolyte out to drop the level far enough that it won't make a mess in the battery-well. I know it's probably not the best for the battery, but I'm planning on replacing it as soon as possible anyway, so I'm not worried about it.

You need to get a multimeter to test the voltages charging the battery. And i've been through refilling batteries before and all of them boiled over and died. I think its just best to get another battery. I think I may have over filled them? Idk what I was doing. And if your bike is not powering all your lights without the battery you HAVE an electrical problem on the scooter. My first guess is the voltage regulator, next guess is wiring 3rd the stator. The wires used on these bike are paper thin and unreliable.

In most cases, a dried out battery must be fully reconditioned. You first rinse it with distilled water several times, then add electrolyte, then do a gravity test and adjust with distilled water to the proper gravity (this is due to residue from the dried out electrolyte, and you should check the gravity several times throughout the process). Then you use a special charger that will charge in several cycles, some with higher voltage or amperage, others with lower. It is never a sure thing bringing back from the dead a dried out battery, and with these small scooter batteries only costing around $35, it may not be worth the effort. I went through more than a dozen uniforms when I was a power generator mechanic (52D) in the army years ago, all due to electrolyte spills, so Be Careful! ALWAYS WEAR SAFETY GEAR WHEN HANDLING ELECTROLYTE!!!
