Pretty sad that it takes all that just to finally arrive at some 'normal' charging specs. Hoping Damin's new RR from that shop will provide some more punch with stock equipment.

It's these voodoo regulators, I'm tellin' ya. Some dude must have died in the plant while working on them and now exists to haunt us all that uses them.

Damin, your scooter must be an exact clone of mine. I've experienced every single thing you have, including the mysterious "touch random wires and it dies!!" The good news is I did finally solve the latter problem. It was the two wires coming off the stator going to the CDI; the connector itself. You would barely graze them and it would kill the scooter, but it NEVER happened when I was ever riding! I cut the stock connector off and made a quick-connect crimp thing.

As far as your charging problem, like I said, I replaced the diode with a relay and that helped.



At least they call them a relay on some sites, it's still a diode:

From that point, it was try about 6 different regulators until I found one that worked well. Some would charge at 17v and overheat, then stop charging altogether, others wouldn't charge at all, others would charge PERFECTLY at 14.5v then DIE after a week. I FINALLY have one that works well, but, I'm too lazy to put it on because the one I currently have (the original stock one) is doing well enough where it juuuuust barely keeps the batter maintained. For some reason if I put the diode back, it ruins everything again.

Hope you find some special thing that fixes it once and for all... i'd be interested!

Maybe the manual was more because it was taking the chinometer into account lol.

I change mine every 1000 miles (after break-in). I'm only at 900 miles total and have changed it 3 times.. so once I finally get to 1000 miles I'll be changing it at each 1k mark.

1000 miles might be a bit early too.. remember, that's 1000 miles on your odometer, and these things run fast as it is. Mine is 20% over! So I guess in actual miles I'm changing it at 800.

On your scooter, yes. They will only come on AFTER you start the scooter. It's due to a diode in-line between the rectifier and the headlights. I actually changed my diode out for a relay, so the headlights come on when the key is on. Reason I did it is for steadier light output. At low low idle, since the lights were previously driven off the stator/rectifier, they'd blink a little bit. Relay made it so they would feed off battery power and smoothed out the voltage. Also, for whatever reason (probably due to a bad diode), the relay seemed to increase the charging voltage to my battery a tad bit.

JR will be able to offer more complete info on this.

Mine doesn't get to 13.5 either; acts just like yours, but it keeps the battery charged so I'm living with it. If you ever go to the SD forum you can find my long thread about it.

Let me tell you something I've learned about these Chinese regulator rectifiers.. they all act differently. My current one acts like yours. My 2nd one died in a week, but would go to 14.5v until then. My third one went to 17v but would overheat and die after 10 minutes until it cooled. My fourth one acts like my second one, but is smaller and doesn't have the same amp output, but I keep it as a spare. It's actually the exact one that JR posted in the first eBay link. Notice that it's smaller than the others. Cruiser66 uses that one, but only runs with one headlight on for that reason.

My current on also has random days where it decides to charge at 16v.. don't ask me why.. well I know why.. they're cheaply made lol.
