Thank you man, very helpful! Your a great instructor!

[@kennethmorgan2704]

Excellent explanation!

[@PaddyO1958]

Nice job explaining the procedures. Well done. Thanks.

[@KevOzY]

Best vid on youtube about testing

[@Sitka_Blacktail_Hunter]

Thank you ! Looks like I have a short to ground . Any idea where I should start looking ?

[@tylerhutchens2340]

thank you, this was a very informative and well explained video, really helped me mentally to tackle my project. Thanks!

[@rmatvmc]

Glad it helped!

[@candacepovia517]

I bought new/used stator to replace old one on quad and not gettin any readings from new stator or from one on quad now.. please any info would help

[@dlbro8460]

Very helpful, great video! Thanks 👍

[@hectordelvalle9984]

super professional , thanks

[@damsela8342]

Greetings, everything is well explained,thank you for posting, is realy helpful. namely, I have a problem with my Tuono rv4, the stator burned and I had to buy a new stator, so when I was already changing the stator, I also bought a regulator. I changed everything properly, but no voltage comes out of the stator during the test. I tried to test according to your instructions, I don't have such a voltmeter, but I figured it out on mine, I tried everything but it doesn't charge my battery and I'm already a bit crazy.

[@s2perman]

Excellent, thorough.

[@JH-tf2yn]

My ATV won't run with the stator unplugged. Is there a way to do the dynamic test in my case? Thanks

[@user-dk5yi7uu5z]

Hello in my atv (access lander 300) in dynamic test on stator show 3.5 acv , 3.5acv and 6.5 acv. The other test is good but not charging the battery. The problem is the stator?

[@dimitrisaab7638]

Hello from Cancun Mexico,please i need advise On checking my stator, working on a 2005 Honda Varadero 1000 , did my static test and the service mannual says I should have 0.3 to 0.5 ohms but my stator reads 1.7 on all three Phases. The dynamic test I did at 1000 rpm 24 Volts AC At 5000 rpm 65 volts and at 6000 rpm 100 volts AC if you can help me please I already burned 3 regulators , thank you very much....

[@videoarchiv6938]

if i get a high reading when measuring the sensor and ground and the position sensor is done can there be a spark at all? if cdi is powered by battery? and first i thought the stator windings were torn but its only this thin yllow isolation wire that is ripped on one side. does that mean anything?

[@Mphonik2013]

I am assuming if you are able to do a dynamic test of voltage output from the stator with it disconnected it is not a component needed to achieve spark? Only sending AC power to the voltage rectifier and then charging the battery? I am not able to start my Polaris 570 Sportsman engine turns over but no spark. Only test that has failed so far is the Crankshaft Position Sensor which I have on order. ohms tested 1000 on the three yellow leads coming off the stator nothing on the CPS sensor. That is where I am starting. Don't want to have to remove the coolant and and stator cover yet but I was wondering if I could figure out if the woodruf key sheared by checking voltage by turning over the engine with the starter obviously without spark I cant get it running but thought if the key was intact I would see a small voltage gain at the yellow leads when I turn over the engine? If the key is sheared no voltage should show, if its intact I should see something as I assume the magnetic flywheel spins when you use the starter?

[@nickolasedmunds]

Well i have a artic cat from a friend im working on the rectifier burned the stators wires but still ran when i hard wired it back together when i replaced the rectifier it stoped running before hand i think the rectifier fried the stator it was 1.5 ohms under 1 ohm spec but the brain i think wont let it spark without a working stator is that bad 1.5 ohms its 3 yellow single phase

[@alicenfred]

My stator resistance test came in at 0.2 ohms, the manual says it should be 0.19, is this good? This is on a 2007 Polaris Ranger 700, Thanks

[@garychios]

HI, I am getting output from the recitifier for 14.x volts, but the batttery is not taking a charge at the terminals. Does a fusible link exist between the recitifier and the battery? Been looking but cant find anything

[@fotoreke3282]

hi,i want ask that those all 3 white wires what goes from stator to rectifier,does it matter what stator white goes to recrifier white,or those ase same how you connect,just what ever white to white,if not have couplin anymore and wires was connected by sugar cube connector?

[@AnythingthatRuns]

Predator 500 question What voltage should be coming out of white blue wire to spark coil?

[@TheLoner801]

Can you confirm this for me? I have a polaris youth outlaw 50. The 3 stator wires are different colors. All three of those wire when tested to ground show resistance. This means it's bad right? But the new replacement is the same way. And is this a single phase?

[@mapo130]

Great video my friend ...thank you !

[@theadventureral-jaberi1646]

it will be great if you show us how to remove the stator . thanks for the video it help me to test my rzr stator.

[@rmatvmc]

*بو عبد الله الجابري* Thanks for watching!

[@Great_XicoZe]

Great video! Hope you can help on this issue: A few days ago, while riding my SYM VS 125, a lot of smoke started coming out of the front of the bike and the engine started to fail. I turned off the ignition and cut the battery current. At home I took it apart to see what was going on and the rectifier was visibly burnt. I took the bike to a workshop where they changed the rectifier and the battery, but they didn't solve the problem. The new rectifier continues to heat up a lot and too fast, as if something is short circuiting. As they couldn't solve the problem and it still cost me a few €€, I picked up the motorcycle with the fault. Tests i have done: - the battery is new and has 13.1V before the starter - with the three yellow wires from the stator connected to the rectifier, the bike works fine at low revs, fails at medium and the rectifier heats up uncontrollably; with these wires disconnected from the rectifier, the bike works well at any speed, but as we know, the battery is not charged - at idle the 3 yellow wires measure about 40V from stator - the resistant test on stator show equal values on three wires; no ground conductivity; no open circuit on each coil - apparently all the masses are well connected. Any idea what it could be causing this recurrent failure of the rectifier? Note: traditional G6Y carburetor engine with electronic rectifier and CDI, year 2010.

[@rogersmainerogers5752]

Can u tell me whay my atv stator keeps burning out I changed it about 4x

[@billyward458]

I had a man work on my 2005 artic cat he hook up a 24 volt drill battery to it now it won't start or turn over and my dash light comes on but no digital stuff comes on and as soon as you turn key on it pops the ignition fuse I need help plz

[@jakedehahn5475]

Great video!! I've tested my stator a million times passed the static test but on the reading it fluctuated a lot it wouldn't give me an exact decimal it fluctuated between 0.6 and 1 on the dynamic test at idle it was 20 volts AC at 3,000 RPMs. It was putting out 60 volts AC so I thought my stator is good it keeps passing the test . But my VRRs keep failing and the last one got so hot it melted the plugin from the stator and I know a bad plugins can cause it to heat up because of the connection. But this connection was good right full of dielectric grease I even added a couple extra grounds new battery that can be a cause of a failed VRR I have gone through three and the previous owner had put one in it I haven't any extra accessories I'm really stumped here any info would be greatly appreciated 16 RzR 1000 turbo

[@mmnelson1509]

Donde lleva el termostato el Polaris Scrambler 400 cc 2 tiempos ???? Gracias

[@beznds]

thanks a lot

[@coreyreynolds9239]

I got a grizzly 660 2005 and it won’t spark no matter what I hooked a test light up to the wire going to the coil and hit the starter button and the light didn’t flicker could that be the stator pickup

[@korbinstudnicki3510]

Did you figure it out?

[@zeinabhamieh6674]

I changed my stator but is still doze not work

[@radhouanebenachour1272]

Nice

[@jasonmcginnis8607]

I’m reading voltage to ground, so does that mean my stators insulation is grounded to the frame?

[@Sugarkryptonite]

You mean continuity to ground from the coil? Then yes

[@tonsta1703]

great video. if your getting fuel and spark and still no start, could it still be a faulty stator?

[@rmatvmc]

Do you know if you are getting proper compression?

[@mastax1234]

So basically what your saying it's not very likely for a stator to go bad. But a voltage regulator cdi would be the most likely culprit

[@208flatbedOO]

Great videos! I have an 07 kjng quad that when i test the stator it tests .2ohms but the service manual specs .4ohm to 1.0 ohms. The ac output is within spec of 85 to 90v at 5000 rpm. How can this be? Ive replaced the regulator/rectifier already. And it gets too hot to even touch it! The quad still shuts off randomly, but im thinking its because of the regulator. Any ideas? Thanks for the awesome how to videos! I get 90 percent of my parts from you guys!

[@g0guletu]

did you ever solved this problem? I am dealing with the same thing on my king quad. it melted the regulator connector, but when testing it, it seems good...

[@208flatbedOO]

@@g0guletu i didn't. The customer became inpatient. I was about to strip the harness out and check for a shorting wire or something. The stator even tested good.

[@moniependergrass831]

Test a stator for teryx 4 800

[@Rickywhite357]

I have a 2020 Polaris sportsman 450 where do you get a good Service manual????

[@rmatvmc]

Polaris has them available direct from them. You can check those it out here: atv.polaris.com/en-us/shop/maintenance/service-manuals/9940287/

[@anthonyrenaud8517]

do I have a bad stator if it dies when it warms up?

[@bjo7964]

anthony Renaud it’s probably your CDI, tap on it lightly when it acts up and see if it goes back to normal

[@jiapaguilar2495]

What year it’s the 450r? And where i can get the seat cover?

[@rmatvmc]

it's a 2008 and it's our attack seat cover! www.rockymountainatvmc.com/p/1060/61023/Attack-Graphics-Factory-Seat-Cover

[@jiapaguilar2495]

Rocky Mountain ATV MC ok thankyou there!

[@lifewithron4466]

will a w2970 tool work with this im new to the meters

[@urinesoakedtroglodyte5764]

I think it should

[@newscooler12316]

Will a bad stator cause over charging or no charging?

[@Sugarkryptonite]

Over charging no, no charging yes

[@kyledc6402]

R u an electrician? Reminds me of labs in electrical school.

[@mattbrewer9519]

Where can I find a service manual for a 2016 rzr turbo that shows all those specs? I found a generic one that’s 418 pages but doesn’t show ohm ratings or anything

[@rmatvmc]

We offer the Polaris OEM service manual that goes in-depth and will be much better than a generic service manual. You can check it out here: www.rockymountainatvmc.com/parts/polaris-oem-service-manual-p?v=12671

[@aStrayforMyTime]

Good side of Stator Salad

[@rodneywise6773]

How do you know which one is your yellow one your yellow two and yellow three

[@rmatvmc]

It doesn't matter. Start from left to right and give them numbers. The numbers are just to help you stay organized and make sure each wire gets tested with the others. They are all connected, so you are just checking that there is low resistance between all of them, and that they are insulated from ground. -Charles

[@MORBID21]

@Rocky Mountain ATV MC Mine stopped charging after the stator got really hot,after half an hour or so.And i know its the stator because i replaced the regulator/rectifier and still the same until i replaced the stator. So my question is,how can you tell if the stator has my kind of problem before it gets hot and stops functioning Thank you for the great videos

[@bewimotos]

you might have a shortage on the winding when it gets hot. its a common failure

[@knotkool1]

my battery is not charging. stator tests are good. voltage regulator tests good. ...now what?

[@DisasterInExile]

Open loop

[@JoeRocket-sf6qs]

Ya only did three phase not all of us have new bikes…duh.

[@Peanutbutter44_ur12]

This is in depth, but wouldn't it be easier to start your machine and unhook your battery? If it runs without the battery, everything is working. If it dies, you have a charging issue

[@davedunn2124]

Sure. But if it dies what now. Theres an issue but wouldnt it be nice to know if you need to buy a high dollar stator or a voltage regulator? He shows how to troubleshoot not guess

[@Peanutbutter44_ur12]

@davedunn2124 stators don't normally go bad unless they have been physically damaged in some way. But i guess the connection could fail

[@petemartus8876]

ndd

[@darrellsomers5427]

If it runs you have spark lol what if you have no spark ,its clear your stator works lol

[@annamull2107]

Like how you just blow off the the single phase one... thanks for wasting my time....

[@yourselfdotcom]

And when you're checking continuity to ground change the meter setting 😅
