Hi, I have a headache from searching around trying to find the values of the stator output and total running current draw of a 2008 244cc Jonway YY250T. Please share them with me if you have them.
Thanks for the help.

I believe mine is as well. Its a '08 and I run 2 55w headlights and the cooling fan most of the time. I have no problems with charging. Except the headlights, all bulbs are stock.

Good link Leo.
The reason I need to know this is because I would like to install a voltmeter/ammeter. I need to know the range of amperage so I can select the appropriate meter.

The max output is 20 amps @ 5000 rpm, 240 watts. Less at lower rpm. That is on the Honda Helix with the same engine.

to be on the safe side i would say the running amps for the 244cc stator would half of the max or 10 amps.
you can safely draw 10 amps all day long.
unless ya wanna haggle of course.

My headlights alone are nearly 10 amps.

Well, I guess I should opt for a 20A. I certainly appreciate the answers.

Yes, I'll haggle. ;D The permanent magnet alternators on scooters and motorcycles are different from the alternators on cars. The permanent magnet alternator voltage is regulated by regulating the load to keep the voltage at the set point. What isn't used for lighting, ignition, accessories, and charging is shunted to ground by the voltage regulator. You can safely draw full power from the alternator all day long. You do any way, it's just a matter of where it goes -- into a useful load you want or the shunt regulator load. More useful load on the system, less load from the regulator, less useful load on the system, more load from the regulator. Put another way, if the voltage rises above the set point the regulator shunts more current to ground to bring voltage back down to the set point. If voltage falls below the set point the regulator shunts less current to bring voltage back up to the set point. |

Y'all are awesome. Leo, that link is fantastic. I love those kinds of websites. Keeps me engaged for hours.

I have a yy250t (244) massimo sl250-22. My problem is it won't charge the battery. I have 14.2 at the red wire from the regulator. What would cause this? As you can guess I am a brand new owner!

It is VERY common for these things to come with failed or failing batteries. Try testing the voltage at the battery while engaging the starter. If it drops way low then it's probably the battery. Of course the connections at the battery terminals need to be tight/clean.
