At 3:30 it is mentioned to insert the flywheel key into the flywheel slot but removal of the key was not mentioned when the flywheel was first removed.
How about that nothing to do with changing stator
It was implied that you'd hold on to the key for later use.
Hi, just purchased a brand new battery and it ran like a top for 3 weeks. Went out to start it today and battery is dead. Doesnt show anything on multimeter. Wondering if it's my alternator or voltage regulator. Appreciate any assistance.
I would have called it a stator not an alternator as there are major differences in the definition and parts and teaching correctly helps the whole community. great video.
How long should a battery on these tractors last if the charging system is running fine? Thank you for the video, it's very informative. 👍
Aleast a year for cheaper batteries and probably 3 years for a really good battery
@@conner5611 Hey buddy thank you for the reply and the info. 👍
@@williamsantiago7303 no prob glad to help
I've had the same battery for 10 years
In reality, and to be technically correct, this is replacing the stator. In an alternator, you have a stator and a rotor. On a small engine such as this, the rotor is the flywheel (with the magnets around the inner circumference) and spins around the stator. When the magnets in the rotor appear over the coil in the stator, a magnetic field is developed in that coil and induces a positive (or negative) current and Each time a gap between the magnets on the rotor passes a coil on the stator, the magnetic field collapses and induces an opposite current into the coil. 1/2 of the sine wave is positive and 1/2 of the sine is negative, thus a true AC current is generated. This current has to be rectified to provide a DC current in order to charge the battery or to power a DC accessory.
+AlwaysFreeAmerica Thanks for sharing. Briggs calls this part an alternator. Kohler calls it a stator.
I understand, but a rose is a rose. It's pretty hard to change the basic principles.
The magnets are in the OUTER circumference of the fly wheel. As they pass by the Ignition module(s), an electrical current is induced.
I used to work at Briggs. The assembly lines that made them were called the Stator lines. But the manual calls it an alternator.
It's all in the rectifier
Nice- clear instructions. Thanks For posting. One question - is the alternator looks so simple - no real moving parts - what would cause it to go bad in the first place ??
prob being old. it makes electricity so after a while the diode or something just gets fired over time.
Why does this model have the battery discharge between using the mower
Thank you for the detail instructions. 👍
You're welcome!

Have a great day!
Enjoyable disassembly and assembly video. I could not understand why this new engine created the alternator problem? What I think is it could be a manufacturing fault of you just did it for the video purpose only on a new engine and nice alternator. Regards,
LearningZone Yes, it's a new engine. We make the videos for our customers.
That's all fine and dandy but we want to know how to diagnose a bad alternator not just throw parts at it
JEREMY FOUNTAIN RepairClinic.com has a free troubleshooting system on our website: www.repairclinic.com/repairhelp?TLSID=1773.
A bad alternator will not produce the voltage necessary to charge the battery. A 12 volt battery will need about 14 volts to charge it.
Use an ohms meter to check for open circuit. Also, look for areas where its burned out.
Where is the voltage regulator located on these?
I'm looking for the answer for myself
@@BigSer what I found was the previous owner had done some rewiring to it and I took an old donor motor for reference. The donor had an inline diode that I cut off and placed on mine. It seemed to fix my alternator burning up issue. Or so it seemed. I sold it right away for parts. So I could be totally wrong.
no-one seems to know
do you need to remove battery first?
1:44 Or, braaap the flywheel bolt with an impact.
???
@@ProBrosMac Using an impact (The Milwaukee M18 is a very nice one) makes this an easy job without having to hold the other end of the crankshaft.
I did this on my 22 ho v twin and it worked
Excellent video. I thank you. ✌🏼🇺🇸
You're welcome!
We are always happy to help. If you would like to give us a review on Google, we would much appreciate it: g.page/r/CcVUrahZNozMEBM/review
We hope that you have a great day!
Never the alternator...first check the diode in the wire connector or if its a big engine the diode is fixed on a heatsink.
Hi, The new stator i received came with shims so the stator wont come in contact with the cylinder casting. I realized installed it with out the shims. Are the shims really necessary?
How do you find alternator part number? I looked in manual, doesn't show...I have Poulan XT, Model: PXT195G42. Any help would be greatly appreciated. Thank you.
How does one identify which engine uses what stator. I can't find any numbers on the engine other than it is a 16.0 OHV Vanguard.
I found my engine series number engraved on top of the silver tin cover that has “OHV” embossed on it. It was really hard to see. Had to clean it up and use a flashlight to see it. Then use the series number to look up the alternator/stator, etc.
What about a blown fuse every time you go to start the mower. Turns over halfway until it gets to the point there’s resistance or just before the spark plug sparks and just blows the fuse.
Sounds like a voltage regulator...but 3 years later and I guess you figured that out.
@@joeymitchell3863 - My timely reply to your timely reply...
Good job, you da real MVP - LOL
I need help...
I have a Exmark turf tracer and the problem is that it won't charge, in order for me to start it I have to use jumper wire and sometimes the blades won't come on because of low voltage to battery. I replaced the started solenoid, regulator, flywheel magnet was broken so I replaced flywheel and also replaced the stator. But it still won't start I have to keep using jumper wires :( help please please please... I was thinking maybe the battery wires but I doubt it
Jbolanos10 We would suspect you have an alternator problem.
+Jbolanos10 Repairclinic is erroneously referring to the stator as the alternator, what he should say is he suspects the stator, however you stated you already replaced that. You also state you replaced the flywheel, which in a small engine is the equivalent of the rotor in an alternator. By changing both the flywheel and stator, you have effectively replaced an entire alternator. One thought I have, not having any experience with that brand, would be a rectifier or solenoid. Trace your wires from the stator to see what, if any, components they may go to.
So your mower doesn't have an engagement wire that engages the blades...
We have a craftsman 21 HP riding mower just like this one a YT3000 model.
these icons are a bit much.
Not everyone healthy like u
That’s a nice machine. 21 HP
Dontcha just love these factory how-to videos? Look at that mower: no 5 years of grass wedged into every crack, no oil blow-by gumming stuff up, no crusty dried up wiring or brittle connectors. The hood slides right off, the wires all come right apart and flex like a new condom. Even the nipples on the tires are pristine! I guess it does make things easier to see, but it sure ain't the real world!
That’s what I was going to say. I’m doing this repair and my hands looks like I dipped them in an oil bin
The wires to the alternator that go up under the flywheel came detached. Have to jump it everytime with a jumper pack straight to the starter. Dont have a flywheel puller to get up into there to reconnect the wires lol.
That alternator looks so simple you should just tell people how to re-wind it.
🤣🤣🤣
Is it pretty much the same procedure on a Vanguard 20hp V Twin?
Are all those motor's the same parts tho? Where can i buy a alternator for my lawn mower.
What size bolts are used for the the flywheel puller?
Can I apply rust preventive products to the flywheel without causing damage? Thank you
Yes
I have the craftsman lt2000 21hp 46 inch cut and I can’t find the voltage regulator because it won’t crank on all the way. It turns over once and stops. I have been able to hook up a battery to jump it a couple times but now it will just turn over once and get stuck. I’m assuming this model doesn’t have a voltage regulator and just have to replace the alternator?
You didn't answer the question does it have a voltage regulator or not? if you don't know... just say... i don't know!
@@godnet5079 I don’t believe it had one but I got rid of it anyways and bought a new john deer zero turn was well worth it!
wheres the voltage regulator ??? no word on that !!
Is it possible to download this video so I can take it on my tablet out to the garage where my mower lives?
+Rabbit Kovatch If you google that question there are videos on CZcams on how to so that.
+Rabbit Kovatch CZcams Red allows this.
no!..bring the mower into the house
When charging the battery of a lawn tractor, should I put the setting on 2 amps or 6. How long will it take to charge on 2 amps? Thanks.
idk but i thing 6 goes to battery and 2 for lights
2 amps is better for the battery but 6 will work fine if u need it to charge fast .2 amps is a trickle charge and u can buy a battery maintainer it charges at 2A and senses when it is charged and will stop charging until it drops below fully charged then it will kick in .it is a good idea to use one in the off season 9n mowers and motorcycles
Hi , I have 10-30 volts coming from the alternator as far as the regulator the same as the one as the video. I checked the wire going to the battery and it has 12.2 so the only thing it could be is the regulator
I got a new genuine plugged it in but nothing , not DC coming out and the battery light is still on ? I'm completely baffled?
Thanks
can you tell me how to test them? I don't know how to use a meter box.
does this alternator fit any mower?
+bluejokerwm No. It is specific to the engine we created the video on.
is this video titled wrong? shouldn't it say "battery keeps dying?", instead of mower (engine)?
Updated thanks!
I need help please, i have a john deere 111 mower with a briggs and stratton in it and i used it for 3 years plowing snow, last spring the stator burned up in it ( started smokeing really bad) and now every stator i put in gets really hot and starts to do the same thing, please help fast
We recommend looking for a shorted wire or battery. You can try disconnecting the wire that connects to the battery to recharge it and see if the stator coils still get hot. There should be two separate circuits from the stator. One DC output for the battery may have a voltage regulator that may be shorted and an AC output for the lights. Looking at a wiring diagram for your model may help.
+Matt Rohn Hey Matt, some JD's use a rectifier, usually attached to the shroud of the engine, that could also go bad and present you with the symptoms you describe. They're pretty inexpensive. To find it, follow the wiring from your stator to the connector. It should also be said that not all of these use a rectifier, so just be aware.
whers the voltage regulator?
Dual circuits stators (alternators) don't have one. They just have a diode instead. I found out the hard way tearing my mower apart looking for the regulator 🤣
Could just be the in series diode by the connector... Why wouldn't you test everything first instead of replacing the whole thing instead of a 50 cent part?? Oh.. never mind, I think I know why!
Can u just cut out the diode and splice a new one in
Diode? You got a video to show replacing?
@@ProBrosMac The diode can only go in one way for the charging circuit to work.. They usually have a white band showing the polarity. Solder the new one in the same way you take the old one out, taking note of the white band.
How much capacity battery can be charge with this alternator? 60 ah?
Looks fairly easy. Just have to rent a puller from advanced auto.
You can probably buy a simple puller from Harbor Freight for less than the cost of a rental and then you'll own it. Ask me how I know :)
@@pj2418 isn't rental FREE you just use your CC to put a deposit in case you damage it or fail to return?
It is a stator not an alternator
I do say that is the stator tho
Lol. I think someone worried they might get sued!
Mine is a craftsman
Is this the only thing that would keep causing a battery to die? I've had this problem with a Scotts Model# S2046 since it was new.
no multiple things can cause it this only the source of power
James Flores Wonderful.
Luigi Provencher id look for chewed wires shorting out or a faulty key switch
James Flores I was thinking that it might be the switch in the seat but I'm not sure. I've got it all apart right now because I had to drop the transmission just to get to the solenoid.
Luigi Provencher jesus the switch in the seat only grounds the magnito to kill the spark that wouldnt do it
Ptetty smart briggs to put the alternator under the flywheel. Do your engineers go to the same school as Audi's???? Unbelievable. Come on make it simple for gods sake. Im not saying this is super hard but im 76 and its a little cumbersome. but whatever. Thanks for the vid buddy
John R Thanks for the feedback.
+John R It is not just Briggs & Stratton that does this John, most small engines do it this way.
my briggs motor is older than me the stator rotor charging system still works as well as the magnito
Why have a robot speaking?
TIL a moron could do this (me).
