Hello Dawgs,
Charge my scooter all night on battery charger. Starts up fine in the AM. Ride it 110 miles non stop. Turn it off, then go to turn it back on right away and its dead, no crank nothing. Put it back on the charger and cycle repeats. Am I looking at a new stator or battery? Its a 2007 JCL250a (MC54250b clone) and it has about 4500 miles on it.
Thanks all, Dom1309

Ya, that was sort of my problem. I owned no electrical equipment to be able to tell if it was the battery or the relay switch. So I ordered a relay switch and foundout it was the battery after all. So I own a extra relay switch. It really doesn't matter, because eventually I will need a relay switch anyhow. More the nuisance of not knowing for sure. lol Attachments:

Is there any way to figure if its battery or stator without electrical equipment? Based on my problem above, does anyone have any suggestions on what it would be?
Thanks Chas

Some of those small 2-6-10 amp chargers they sell at Wal-Mart will tell you if the battery is bad. They give a fault code. If not charge it up and take it to Autozone and let them check it. Those small voltmeters don't cost much and good to have for other things.

if the stator is bad then your scoot will run until the battery voltage gets too low to support high RPMs. when this happens the scoot will not run at high RPMs but it will idle.

Took battery to Advance Auto (thanks revets). Battery is good. So am i safe to assume Stator is bad? Can someone lead me to a reliable site to buy one?
Thanks Chas

Now Im reading rectifier, etc could be why my battery wont stay charged. I dont have testing tools to check these things out. Can someone lead me in the right direction here?
Much appreciated, Chas

Thanks Chas The answer is any, all, or none of the above or something else. Go to Harbor Freight and spend five bucks or less for a volt ohm meter. Diagnosing electrical problems without one is futile.

Jim, The stator is the scooter equivalent of a car alternator. It supplies power to operate sum of the different components and charge the battery while the engine is running.

The stator is behind the Flywheel on the right side. It is behind the FAN that blows air into the shroud around your engine to help keep it cool. BUT to pull the Flywheel off to get to the stator you will need a Flywheel Puller. Lefty And this is what a stator looks like: And let me say this, it is most likely your Regulator/Rectifier and not your stator. The Regulator/Rectifier is the one that actually sends the volatage to the battey to charge it.

Jim, Here is a link that shows basically what a Regulator/Rectifier looks like. www.oregonmotorcycleparts.com/VRRPM.html I don't own one of these scooters so I don't know the exact location the the r/r is located. You will have to look around under the covers but you should be able to find it in short order. The location you can find all of this information if you use the search button at the top of the page below the Scootdawg Forum banner. Be sure to login or it will make using the Search Botton harder.

Ive been away for a few days, but have come back to a wealth of information!!
Revets, YES its the Linhai clone. Thats the stator I need then IF its the stator.
I have dismantled the plastics down to where I can see where the statore goes into the engine. There are 5 wires coming out of the top of the engine. I have also identified the r/r. Its on the right rear of the scooter attached to the frame. Now, my questions...... these 5 wires go to various places, including the r/r. How do I check the stator to see if its the culprit? I am told I need a multimeter(?), but which wire(s) of the 5 am i checking? What readings should they have? Also, how can I check the r/r? We are really close here guys. Electricity, ohms, resistance, is all a foreign language to me but if someone could give me the reading on which wire should read what and when, I think I can do it!! Thanks again in advance to everyone helping me get back on the road!

Much appreciated, Chas you definitely need some sort of testing device, either a test light or a volt-ohmmeter. a volt-ohmmeter ( VOM ) would be better because it will measure resistance. you can rig up a test light with a 12 volt light ( turn signal or brake light will work ). you will need a light socket the bulb fits in and 2 long ( about 2 feet ) pieces of wire. if you aren't sure about what you are doing then get someone that does. be especially careful when the scoot is running, coil shocks can be painful, not to mention burning out your light or ruining your meter.

Thanks for your help! Where is the Stator located on the scoot? Anyone got pictures or a map showing how to get to it? on my 244 the stator can be accessed by removing the 2 hoses to the water pump and the the external oil line then removing the 8 screws that hold the the right side crankcase cover. the stator comes off with the cover and is held in place by 3 screws. the ignition pickup is also located inside the cover. DO NOT interchange the external oil line screws, you will ruin your engine if you do. there are 3 of these screws, one is right above the starter and will only fit in the hole it came from. the other 2 are the ones to worry about. one goes into the valve cover the other into the cover you are removing. MAKE ABSOLUTELY SURE you get these 2 screws back into the holes they came from. BTW a honda helix right side crankcase gasket will fit

I am told I need a multimeter(?), but which wire(s) of the 5 am i checking? on my scoot all 3 of the stator wires are yellow and plug directly into the R/R. the fourth wire is yellow/red and goes to the CDI. the fifth one goes to the choke.

I see that the Regulator/Rectifier cost about a $100 but I am not sure this is my problem. My scoot won't start at all. All the power comes on but won't start. I bought a new battery and still won't start. So what is the steps I should follow to narrow down the issue and find out what is wrong. I do have a voltameter.
PS. I have checked both fuses which are good. One is a 10amp and the other 25amp. Is these the correct sizes? Which one goes where?

I see that the Regulator/Rectifier cost about a $100 but I am not sure this is my problem. i paid 35 bucks for mine. turn your key to the run position then: check if the CDI is getting 12v power. check if the coil is getting 12v power. start cranking the engine and: see if the CDI is sending pulses to the coil.

Chaz: I'm going to chime in late here and for that I apologize. Do you ride with the lights on? If so try a ride without the lights on and see if you get the same problem. It maybe that your lights are using more amperage than your stator can put out to keep the battery charged. If you take a ride with the lights off and the battery stays charged then that is the problem and there are several fixes you can make. You can purchase a digital volt meter on ebay for almost nothing and it will tell you how healthy your battery is at any given time (amp meter will show the numbers you are using plus and minus). Go to the trike section on this forum and there are some posts that may interest you. vr, Lee

I finally had a chance to get out and play with the multimeter. First, I had disconnected the battery, with the battery disconnected the battery itself read 12.9v.
I then hooked the battery up, with it hooked up, it read 12.9v, started the scooter and ran it for a few minutes and it decreased down to aprox 12.5. Turned it off and it slowly came up to 12.7.
I then started it up, and disconnected the positive battery cable and hooked up multimeter to the positive wire (not hooked to battery). It was bouncing anywhere between 4.4-4.7v. I revved the bike up to about 4000 rpm and the reading went up to 5.8v. I then idled the scooter and it went back down to the 4.4-4.7v range.
Obviously the scooter is not getting a proper charge. My questions;
1) What SHOULD the scooter be reading when I had the positive wire disconnected from the battery and i was getting the 4.4-4.7v? Is that where it should be getting the 14.5ish volts?
2) What do I do now to determine whats wrong?
Again, any and all help is appreciated!
Chas

The way you test the stator on your bike is easy. Unplug you stator at the connector. You should have have around 1 ohm resistance between each yellow wire and you should NOT have continuity to ground between any of the yellow wires. If you do the stator has a short in it. If it is bad you want to make sure you get a new gasket for your righthand crankcase cover. You do not need a flywheel puller to change the stator on that motor. Drain the oil and just remove all the bolts on the right hand cover. I like to make a drawing of the cover in a cardboard box and make holes where all the bolts go. That makes it easy to keep track of where all the bolts go because you don't want to get them mixed up. The cover can be a little hard to pull off because of the gasket and the magnetic pull of the stator to the rotor.

I concurr with Great big Guru Dawg... Make a picture on card board, Pull side cover off, and put the bolts in the respective holes on cardboard,you can't go wrong... now trace yourself a new gasket from material you bought at Fleet Farm or auto store, torgue bolts down to no more than 8 ft pounds each. No fly wheel puller needed here. stator is attatched to the inside of the right cover. you will figure it out once you get a look at it.. very easy to replace. MC-250B of mine had the larger of the two stator sizes that are for that bike... make sure you order the correct one.. don't get discouraged, just do it..
