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.

[@IFIXIT4U]

Thank you

[@budgillett9627]

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.

[@IFIXIT4U]

Thank you

[@TimothyJamesDean]

Thanks for that! I learned how to rewire my entire Husq tractor from other videos, and how to rewire my charging system from you.

[@IFIXIT4U]

Glad it helped. Thank you.

[@joeyware1927]

fixed my customers mower withing the first 4 minutes of watching this video!!! great job and thank you!!!

[@IFIXIT4U]

Fantastic!

[@waiakalulu2472]

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.

[@IFIXIT4U]

Thank you very much! Glad it was helpful.

[@123hotdog111]

Best and most in depth video I've ever seen. Thank you so so much.

[@IFIXIT4U]

Wow, thank you!

[@chadfield376]

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:-)

[@chrisa1125]

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!!

[@jasonmelancon8096]

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.

[@jasonmelancon8096]

Also if your battery gets low enough the engine will not run.

[@fourpawz57]

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.

Thank you, this is what i needed to diagnose my mower

[@IFIXIT4U]

Thank you

[@timjohnson804]

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?

[@IFIXIT4U]

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

[@mchristofas]

Do you only use factory branded parts? I have an older FC420v and wondering if all parts are available (many show up on amazon etc)

[@IFIXIT4U]

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.

[@jasonlanders9289]

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?

[@IFIXIT4U]

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.

[@IFIXIT4U]

Much appreciated!

[@daviddavids2884]

hey, could you tell me what '15/20 amps' means, as a pm alternator output rating. thx

[@IFIXIT4U]

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

[@doozer211]

Great video, thank you! Do you think a bad voltage regulator could cause a pto switch to melt when Engaged?

[@IFIXIT4U]

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.

[@davidrivera8385]

Great video had this problem today on my hustler. Thank you Sir

[@IFIXIT4U]

Thank you.

[@DanielVia-zb7hr]

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?

[@IFIXIT4U]

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

[@richardmulder8542]

My NEW stator is only putting out 13AC volts. Is it possible the flywheel is bad? Magnets are attached and magnetic

[@IFIXIT4U]

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

[@richardmulder8542]

@@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

[@styga1969]

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?

[@IFIXIT4U]

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.

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

[@IFIXIT4U]

No. Coil has nothing to do with charging circuit. If you have to jiggle the key it may be a bad ignition switch.

[@Guerrero1187]

@@IFIXIT4U when I disconnect the battery while it’s running the engine shuts off.

[@Guerrero1187]

@@IFIXIT4U can the ignition switch effect the charging?

[@jessemalone8363]

@@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.

[@bobreichel]

My kohler 23hp keeps blowing the fuse. Stater seems good not sure why its doing this. Any idea? Ordered a regulator just in case.

[@IFIXIT4U]

Could be a short or pinched wire or a hot wire grounded. Check all wires for damage including head light wires.

[@squirrell500]

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.

[@IFIXIT4U]

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

[@thecuttingforce]

Thank you for this

[@IFIXIT4U]

Thank you

[@lc9716]

But a new stator on my kawasaki and I'm not get any reading thoughts?

[@IFIXIT4U]

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

[@stevenbeasley1]

how much did you charge to change the stator ?

[@IFIXIT4U]

To many variables to have a pre set price. Cant quote prices here. Thank you

[@IFIXIT4U]

I would look for the wiring schematic. Probably find it on line. Good luck. Thanks.

[@kennethfannin8707]

i finally figured it out ,,, thanks all

great video

[@IFIXIT4U]

Glad you enjoyed it

[@aaronclark1599]

What about a Honda 24.0 V-Twin?

[@IFIXIT4U]

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

[@aaronclark1599]

I checked my stator at 1/2 throttle and get 0. Should I try it at full throttle?

[@IFIXIT4U]

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.

[@rcmoot]

You can thank engineers for making it hard and making you money.
