I’m an old duffer from Nebraska and am trying to learn some in depth details on repairs other than just plugs, carbs and gaskets. This was very very informative for me. I’ve subbed and will be watching. IMO an extremely educational video with great visibility, explanations and no horrible background music!!!!! A real BIG DEAL for me.
I have an electronics background and have struggled to find a simple video that showed me the charging system and how to test it. This is so simple and straight to the point on how to test and troubleshoot. Thanks for the information.
Easily one of the best videos out there to help diagnose these types of charging systems. Much obliged to you for making this how-to video and for you to drop your scholarship on the subject for us folks just learning these things.
Thanks a lot. You do a fantastic job showing how to check charging system. You are exactly what I was looking for. Thank you very much & keep up the great work
I enjoyed your testing which was simple to understand and Thank you for your knowledge so people like me might have a way to fix my lawnmower and save some money.
Best mower charging system check video I am have seen:-) I especially like the parts where you show your multi-meter settings to make sure rookie DIY’slike myself are on the same setting to perform the test:-)
Just wanted to add to all the other great comments you've received on great job on sharing your knowledge in how to check and repair the chargeing system very well done and explained to understand keep doing your videos thank you so much..
My problem is after I cut for a couple of hours, the engine won't start... like the battery is dead. I can charge the battery and it will start.... brand new battery. I've had it (2008 Exmark Lazer Z with the 28hp Kawasaki) at the local repair shop 3 times and they still can't fix this seemingly simple (for a trained mechanic) problem. So I've came to the conclusion that it's on me to figure it out and to find a new mechanic. Your video is just what I was looking for to assist me... THANKS!!
It’s going dead because your electric PTO is dragging the battery down because it’s not charging. Make sure you battery is good and do the check in this video.
So if the stator is not putting out anything is the 12V battery providing the power to the CDI for the spark plugs? What is providing the timing pulse to the cdi boxes to provide the spark at the proper time? How is it running with a .5v stator output? is that enough voltage to run the CDI wich in turns sends juice to the spark plugs to run the motor? I guess what is the min output from a stator and have the engine run fine like in this video?
On a simplicity zt2354 we don’t show battery voltage at the B terminal of the reg. Supposed to be an “inline fuse” somewhere. Can you confirm this? Can’t find one anywhere. Can a new wire just be run?
I would fix the problem. I would not run a new wire. I do not have the specific schematic on your mower and cannot answer specific questions about your wiring harness. You can probably find that info online. Good luck. Thank you.
the first engine shown at very beginning of the video has a ground wire from regulator to engine bolt. The engine that you tested does not have that ground wire. Is there a difference in performance with or without?
The voltage regulator will not work unless grounded. Sometimes they use a wire, sometimes they use a tab. Sometimes its grounded through mounting screw from behind it. Thank you
OEM parts is my first choice but sometimes you have to use what you can find. On older engines parts are sometimes harder to find. Aftermarket parts are ok but you get what you pay for. Good luck. Thank you.
Keep in mind that on a regulated system. System will only produce what is needed depending on electrical load. System will produce a maximum of 15/20 amps depending on engine RPM that is set by equipment OEM & size of the magnets in the flywheel. 15/20 amp system is more than enough for a mower with lights and electric pto clutch. While testing DC amps from DC+ regulator to + battery, 4-8 DC amps would be normal. If you apply a electrical load you will see the amps go up. I hope this help you. Thank you
The regulator puts out what is demanded. If you have a good battery and your electrical system is in good order. And you are not running any other electrical devices. Now if the regulator is putting out 16 amps I would say replace it. Thank you
Is your stator like the ones in the video? ( 2 wires)? Are you connecting the stator to the volt meter exactly the way the video shows? Both meter leads to stator? If so. Sounds like your new stator is bad or the wrong one. Thank you
@@IFIXIT4U thanks so much. But overnight I actually thought of the problem. The magnets came off of the fly wheel which I glued back on, but I think I got the orientation wrong on three of the magnets. So it would make sense that I’m only at 13 AC volts. I got a move the fly wheel and check those magnets. Thanks for your response. And yes I connected to the two wires from the stater
What if you have broken or missing magnets on the flywheel? What is the factory recommended ohm specs for the 3 engines in the video? How will you know if you are producing enough AC voltage. By the time you read this I have already tested the stator voltage and sitting down drinking coffee waiting on the ohm specs.
@@Guerrero1187 yes the yellow wire on the switch is the charging wire, check it for burn marks or if its even still on the switch, that yellow wire goes all the way to the regulator on the engine, if possible check resistance with a volt meter , shouldn’t read very much resistance.
I've got an older Koehler ch740 and every time I disconnect it from the battery it will die. Is that normal? i have replaced flywheel, stator, and regulator.
Yes. That is normal. You need battery power for the fuel solenoid on the carb and most of the ignition systems on those early models. The charging system can shut down if no battery is present in the circuit. Also the equipment wiring harness plays a roll in that. Removing the battery power while engine is running tells me nothing about the condition of the charging system. Also its hard on the voltage regulator and other electrical components. Thank you
Do the battery & stator test the same as video. You can test DC Amps buy pulling the correct fuse and using meter probes. By the time you do all 3 test you should have an idea of the problem if you have one. Video coming soon on this engine. Thank you
There are only 4 possibilities. I will let you narrow them down. Stator, flywheel magnets, meter, Person holding meter. Make sure the stator is correct OEM stator. Make sure magnets in flywheel are good and not broken. When testing stator use AC Volts, see video. Try a different meter. Connect leads directly to stator, see video. Runs engine at full throttle. see video. Thank you
my problem is ,,i bought a husqvarna zero turn ,, all the wiring looked like spagetti ... ive been working on it for a week and just cant figure out where the wires go once they leave the motor ,,,,driving me batty ,, bought a new amp gauge and have no idea what wires got to it or where from ,, baffled to say the least

Very well done, you made this problem so much easier for me to understand and fix my problems. Thank you
Glad it helped
A very informative and useful video! Clearly explained and concise! Well done!
Glad it was helpful! Thank you
Thank you. Very helpful and greatly adds to my understanding of small engine charging systems.
Glad it was helpful! Thank you!

It’s going dead because your electric PTO is dragging the battery down because it’s not charging. Make sure you battery is good and do the check in this video.
Also if your battery gets low enough the engine will not run.
Electric pto clutch or switch. Just trying to learn to do my own maintenance @@jasonmelancon8096
Thank you. Excellent video. Very useful.
Best wishes for the year ahead.
Glad it was helpful! Thank you.
Thank you sir for your well explained video. When you DIY you need all the help you can get.
Glad it helped
Great video. I have a much better understanding of the charging system and how to test it. Thanks.
Thank you!
Awesome instructions sir, could you possibly show a Briggs charging system that well anytime you can please ?
Thank you. Sure will.
Best TH-cam video on the subject!!!
Thank you very much!
Love the video IFIXITFU. Well done guys. Very clearly worded and well explained. I am a fan.
Much appreciated!

Thank you.
Where does the hot wire go to like the battery side of the solenoid or the starter motor side of the solenoid or straight to the battery?
One of the better videos on this
Thank you
Excellant vidio. Helped me diagnose my dead stator on a John Deere with a Kawasaki 25 hp engine. Thanks
Thank you
Excellent video, thorough explanations, variety of examples! AAA+++

Awesome vid!!
Very well explained 👍🏻👍🏻
Glad you liked it!
You sir are awesome. Super-awesome.
Thank you kindly!
Great video, thank you!
Do you think a bad voltage regulator could cause a pto switch to melt when Engaged?
Probably not. Most likely its a bad PTO Clutch or direct short in hot wire to PTO clutch. PTO clutch should pull 3-5 amps DC. Good luck. Thank you.
hey, could you tell me what '15/20 amps' means, as a pm alternator output rating. thx
Keep in mind that on a regulated system. System will only produce what is needed depending on electrical load.

thank-you very much sir , stay awesome mate !!
Thanks, will do!
Thank You’ll for information and video
Thank you
Thank you so much, your video helped me immensely.
Glad it helped!
What if the regulator is putting out over 16? Would that mean it’s over charging the battery and thus it’s a bad regulator?
The regulator puts out what is demanded. If you have a good battery and your electrical system is in good order. And you are not running any other electrical devices. Now if the regulator is putting out 16 amps I would say replace it.
Thank you
Fantastic work on a sorry designed system.

Glad you liked it. Thank you
My NEW stator is only putting out 13AC volts. Is it possible the flywheel is bad? Magnets are attached and magnetic
Is your stator like the ones in the video? ( 2 wires)? Are you connecting the stator to the volt meter exactly the way the video shows? Both meter leads to stator? If so. Sounds like your new stator is bad or the wrong one.

you are correct on B+ location i was going by mine but they are not all the same thks
My kohler 23hp keeps blowing the fuse. Stater seems good not sure why its doing this. Any idea? Ordered a regulator just in case.
Could be a short or pinched wire or a hot wire grounded. Check all wires for damage including head light wires.
Question .. can’t you just ohm the 2 white wires to the stator ? And see if it shows it open? It’s just a wind of wires?
What if you have broken or missing magnets on the flywheel? What is the factory recommended ohm specs for the 3 engines in the video? How will you know if you are producing enough AC voltage. By the time you read this I have already tested the stator voltage and sitting down drinking coffee waiting on the ohm specs.

Thank you
Awesome video thanks for sharing
Thanks for watching
Can a bad ignition make it not charge? My Scag cheetah Kawasaki 27 hp isn’t changing and I have to jiggle the key for it the start
No. Coil has nothing to do with charging circuit. If you have to jiggle the key it may be a bad ignition switch.
@@IFIXIT4U when I disconnect the battery while it’s running the engine shuts off.
@@IFIXIT4U can the ignition switch effect the charging?
@@Guerrero1187 yes the yellow wire on the switch is the charging wire, check it for burn marks or if its even still on the switch, that yellow wire goes all the way to the regulator on the engine, if possible check resistance with a volt meter , shouldn’t read very much resistance.

Glad you enjoyed it
You can thank engineers for making it hard and making you money.
how much did you charge to change the stator ?
To many variables to have a pre set price. Cant quote prices here. Thank you
What about a Honda 24.0 V-Twin?
Do the battery & stator test the same as video. You can test DC Amps buy pulling the correct fuse and using meter probes. By the time you do all 3 test you should have an idea of the problem if you have one.
Video coming soon on this engine.
Thank you
I checked my stator at 1/2 throttle and get 0. Should I try it at full throttle?
I check it at full throttle. A good stator will still put out AC Volts at half throttle. If you did the test per the video. Then your stator is bad.
But a new stator on my kawasaki and I'm not get any reading thoughts?
There are only 4 possibilities. I will let you narrow them down. Stator, flywheel magnets, meter, Person holding meter. Make sure the stator is correct OEM stator. Make sure magnets in flywheel are good and not broken. When testing stator use AC Volts, see video. Try a different meter. Connect leads directly to stator, see video.

This dude sounds like John Goodman
I look just like him, We could be twins separated at birth.
my problem is ,,i bought a husqvarna zero turn ,, all the wiring looked like spagetti ... ive been working on it for a week and just cant figure out where the wires go once they leave the motor ,,,,driving me batty ,, bought a new amp gauge and have no idea what wires got to it or where from ,, baffled to say the least
I would look for the wiring schematic. Probably find it on line. Good luck. Thanks.
i finally figured it out ,,, thanks all
Kohler over Kawasaki all day long
Thank you
