Nice. I hadn’t realized the lighting circuit was AC. I know a lot of small engine installations may have a separate lighting coil, but as I said didn’t appreciate it may not be rectified. Cheers Terry
As you know Ian, incandescent bubs will work fine on AC as well as DC. Leaving out the diode for the lights just simplifies the circuit. Thanks for dropping in and sharing a comment!
I found this to be really interesting. I didn't realize those small engine stators had two separate sections built into one for battery charging and the headlights. The most amazing thing about this video Terry was how you gained youth and looked 21 years younger from the 8:00 minute mark 🧓 to the 20:00 min mark.🧒 If the white board of knowledge does that then I need to stand in front of it more often. I bet you had no doubt I would notice? haha 😉🤭
I knew that you were always observant Glen. Isn't it amazing how a white board can make you look younger? It's because the light rays reflecting off the white board has been known to rejuvenate the skin and make you look younger. HaHa! 😍
I knew I needed 2 cups of coffee because the presentation rattle my brains a little. Great presentation, just one quick question how does temperature affect any of the measurement????
Thank you Bernarda! Temperature affects measurements because of the higher energy state of atoms. Basically, at higher temperatures, the free electrons are moving faster and have a tendency to collide with the electrons from the source. This collision of electrons will slow down the movement of electrons through the material which creates a higher resistance to the current flow. Here's an article that may explain it a little further for you Bernarda. www.learnabout-electronics.org/Resistors/resistors_01a.php Have a great weekend!
Great presentation.. I have the same motor transplanted on a mower having an electric clutch for the deck drive belt so it is drawing my charge when on to only 11.3 volts full throttle. I dont use headlights. Can I delete the diode and use an exsternal regulator and use both charging wires out of stator to it to run current to both the clutch and charge battery ?
Not sure about that Kevin. I would take a look at the specs for the mower's stator, regulator and compare it to the stator's spec for the 'new' engine. You could also take a look at the stator's for Briggs and Stratton engines which has a regulator instead of a diode.
Question sir, my friends riding tractor is not charging, i bought on ebay a used stator dual circuit . I checked for continuity and ohms on both coils they seem fine but on my ohm meter when i check for continuity on the ac output wire from the coil to the diode dc output i get nothing when i checked both ways ?? It seems i have an open diode or maybe not enough ac v to turn the diode on according to your third video...thank-you very much, STAY AWESOME MATE !!
It sounds like your stator is fine. If your meter has a diode function, use it instead of an ohms setting because if you use an ohms setting, the meter may not deliver enough current to turn the diode on. As there not being enough AC to turn the diode on, this is very unlikely as it would point to an open stator winding which you said you had continuity. Have a great day!
Another excellent video Terry ... been awhile since I revisited algebra, but it all came back! One question ... still trying to wrap my head around tying the A/C headlight circuit back to battery (DC) ground .... I guess the battery doesn't care if the current is A/C or D/C??? Can you explain this a little bit? - Randy
Good question Randy! If you were to check on each side of the wires for the headlights, you would have AC amps. However, remember that the source is the alternator. When current leaves on one side of the stator, it will return back on the other wire to get back to the stator. Although, the DC- wire is connected to the battery, this return current won't go back to the battery. All of this return current is going back through the frame of the riding mower. Hope that makes sense!
my lawn tractor that as a Briggs engine with the same Dual Circuit Charging System when the engine running the battery is charging at around 19 volts the same from the stator wires 19 volt from one wire and 14 volt im gusting for the lights so im just wondering if its normal
Hey Stacey! The 14V for your lights is normal. The 19V sounds a little high and I'm assuming that you didn't disconnect the charging connector near the stator. If so, then you would measure around 19V. It could be normal, but I didn't see this high of a voltage on my mower. The highest for me was around 15V. Check the amperage going to the battery as it could be that the battery isn't accepting any charge. Have a great day!
BASED ON WHAT i OBSERVED IN YOUR VIDEO, FROM YOUR LEAD WIRES TO THE STATOR BODY YOU WILL INDEED HAVE CONTINUITY? I'VE BEEN YES YOU AND NO YOU SHOULDN'T. PLEASE HELP IF YOU CAN. IN LAYMANS TERMS PLEASE lol
Ok gotta take a break before watching P3! I have a lot to digest here. Don't know how you keep all that in your head but great job Terry!
Yeah, it's a lot of stuff for sure Mike. I've been in the electrical field for so long, this material has stuck with me for quite awhile.

SIR MUCH RESPECT TO YOU AS A VERY FINE TEACHER, THANK-YOU VERY MUCH MATE !!
Thank you Roger for watching and for the comment! Have a great day!
Great presentation as always...
Thank you Daniel!
Hats off to you Terry , you dig deep bud . I know how it works but not why :) 👍
Thank you Steve! The why is so that we can cut our grass with all these marvels of physics. 😉

@@stuzman52 So, in this case, the battery is part of the path back to the alternator frame! Ok, that makes sense to me.... Thanks!
@@randymarion2466 Yes, that is correct! 😀👍

Yes Roddy, that is correct. The stator windings would have continuity through them. Have a great day!
