@@doncarlson8391Great video on checking the charging system on a B&S Vanguard. I have a question and looking for your expertise. We have an 18HP B&S Vanguard V-Twin that has a problem charging the battery. After troubleshooting the system based on your video the stator was only outputting 11V (I have a Fluke Meter that automatically detects and switches to AC or DC voltage. I ordered a new stator as well as a new voltage regular. I installed the new stator and confirm that the old one was burnt out in several spots. I clean the magnets and the entire system before putting it all back together. After doing this, the 2 pins coming from the stator is only outputting 19V (specs recommend 28V). I also tried connecting the new regulator and do not get any AC voltage on the output red wire out of the voltage regulator. I am now lost on what else the problem(S) can be. Any idea or suggestions to follow would be greatly appreciated. Thanks.

Thanks for taking the time to share your expertise on this subject. You save me lots of time trouble shooting. Excellent video, just the right amount to detail saved me the cost of a repair manual. Just needed a new regulator !

Nicely done sir. I'm running a 2007 Simplicity Broadmoor and my first thought was that mice and gunk had gotten into the alternator coil, but after pulling the flywheel it looked practically brand new. This was my next culprit. Thank you for the side-by-side good/bad comparison.

Thank you very much for this video. I figured out that my battery was not charging but had no way to tell what has failed. Brilliant video!! You may have save me some money and time. Great job!! Best I've seen.

So so helpful. My voltage regulator failed, and when I tried a new one, I got no voltage out of the regulator when not hooked up to the system. I tried a third regulator and got the same thing. As you pointed out the output voltage from the regulator is dependent on whether or not it is plugged into the system. I never would’ve thought that. Thank you so much.

Great video and just what I needed to diagnose a Scag with 23 HP Briggs Vanguard on it. Turned out to be a simple sheared bolt on the frame that held the negative/ground lead from the battery - but I was ready!

Beware NEW voltage regulators that are bad out of the box. I bought one on eBay, installed it, no charging. Returned it, got a second, again, no charging. After tearing the mower down, looking for faults, I found none. Everything pointed to the NEW regulator being bad. In addition to the AC test in this well done video, I have a few tips for people in similar situations. First off, my mower has a built-in ammeter so I noticed that the new regulator wasn't charging right off the bat. Most mowers don't have those and I can only imagine the scores of people who installed a new regulator thinking their worries were over only to find their batteries dead several months after the warranty on the new regulator was expired. The simplest way to check to see if your charging circuit is working is to start the mower and measure the voltage across the battery. It should read about 14.5V - not 12.7V. The battery needs the higher voltage in order to charge. To test the stator, use the AC test as described in this video. The engine should be at full throttle and actual AC voltage should be what the manufacturer specs say. I also load tested the stator by connecting a 12V light bulb to the output. At low RPM, the bulb will light, at higher RPM, the bulb will blow. Incandescent light bulbs run fine on AC. In my case, the bulb drew about 2 amps from the stator with no problems. Next, I hooked the same 12V bulb up to the mower wire that connects to the output from the regulator. The other bulb lead connects to ground. Then turned on the ignition switch. The bulb lit up indicating there was no break or hidden blown fuse. Finally, I bought a 25 amp bridge rectifier from a local electronics store and hooked the AC input to the two stator wires. The positive (+) output of the rectifier connects to the mower wire that the regulator output wire would normally connect to. The negative(-) output to battery ground. When I started the engine, I immediately saw the full 13 amps going through the ammeter and into the battery. This was proof positive that the charging circuit was fine except for the NEW regulator. It should be noted that the bridge rectifier connections were for testing only and the battery will be ruined if you run it like that for very long. The rectifier converts AC to DC, but does not regulate the voltage to a safe level. Hopefully this will save other people from having a dead battery because their NEW regulator doesn't actually work.

Your comment was very well written, logical and easy to understand. I copied it into my Tractor Electrical Diagnostic notes for future reference. That said, wouldn't the process in the video accomplish the exact same thing? In other words, don't assume the replacement regulator is good out of the box. Connect a bare jumper between the two DC output connections and measure from the jumper - the key being the battery needs to be integral to the testing loop for a valid test?

@n4mwd

​@@MC-hs4mfmost likely not charging. Measure the battery voltage running and then again right after you turn it off. The running voltage should be about about 2 volts higher. Try the bridge rectifier test to be sure.

@n4mwd

​@@Rein_Ciarfellayes if you have an ammeter or something that can measure current you can measure what the regulator is actually putting into the battery. But remember that a charged battery will not take as much current. It's best to put some kind of load on the battery itself. Or simply compare the voltage of the battery running versus not running.

Thanks, helped me rule out buying the more expensive parts. Regulator on the way from Amazon.

It has been nearly 2 years since your Amazon Regulator install... How is it working?

if you have a bad battery, would it make the voltage drop at the battery when checking while running? I hope that is clear, we started the mower and the voltage was 12.57 but the battery was dead... would we loose that much voltage from trying to charge a BAD battery? thank you

Thanks. This solved my problem.

Excellent video !!!

Doesn't a voltage check of the battery with the engine not running compared to a voltage check with it running accomplish the same thing?

Great Video!! Very well made.

Just for info.. some B&S engines only have two wires to the Rectifier/Regulator. One from the alternator (yellow) and one to the ignition switch, fuse and battery.

a bad or really low battery will fry the voltage regulator on a briggs and stratton engine with this style voltage regulator due to overloading the regulator , always make sure battery is fully charged before attempting to run engine

Excellent! Now to hunt up my ammeter: mine keeps blowing fuses

GREAT Video. Thanks!

Agreed on the valves.. A little loose

Same problem...battery running down. I think Bat is ok. I get the ac Volts from Stator, but also get .5 V dc from Voltage Regulator. I am on my 4th VReg change. 3 from ROPS, CA, and a Briggs Box part. I get the .5 on all of them. I see on some videos a Voltage reading of 13 - 14, from the VReg, but like yours, I only got the .5 Volts dc. (until u put a jumper). I wonder if there is a rectifier or etc in the circuit that impedes the current unless a battery is in-circuit, thus the .5 Volt. But I am not confident the Regulators are operating GOOD with only .5V dc, but four new ones in a row?

Thanks. Much appreciated.
