Briggs & Stratton Battery Not Charging - Simple Voltage Regulator Test

Рет қаралды 615,933

PLEASE USE THIS VIDEO FOR INFORMATION PURPOSES AND TAKE ALL PRECAUTIONS WORKING ON POWER EQUIPMENT, FAILURE TO DO SO COULD KILL OR SERIOUSLY INJURE YOU. The battery on my lawn tractor started going dead and I'd notice the needle was staying on the negative charge side of the amp meter so I dug into the charging system and here is what I found. The charging system is pretty simple, the engine has an alternator under the flywheel that puts AC volts into the Voltage Regulator, the regulator changes it to DC volts and regulates the output, the output goes to the battery via a wire that may go through a relay and fuse. If you have plenty of AC volts coming out of the alternator and battery volts (less than 12.5 volts) on the wire going to the battery (at the connection to the regulator), the voltage regulator is the only thing left and is probably bad. What you see in this video should apply to any engine with a 3 wire voltage regulator. Unfortunately the regulator itself can't be checked with a normal volt/ohm meter so this diagnosis is through process of elimination.

Absolutely the BEST explanation on here. There are DOZENS that tell you little or nothing...mostly guys that must have NO one to talk to or trying to show how BRILLANT they are.....

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.

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.

@doncarlson8391 Жыл бұрын

Thanks for watching and glad the video helped you understand the system. It's odd that you can't read the DC output directly out of the regulator but now we know how to check it.

Thank you very much for your excellent video explanation. I followed your instructions on a kohler command 16 HP not charging and narrowed it down to no ground at the rectifier.

This is an excellent video to test the voltage regulator/alternator. Just a suggestion, your tractor is hard starting indicating the need to adjust you valve clearance (too wide of gap causing not allowing the compression to be released properly).

Jim Kelly, you are absolutely correct and I have a video of setting the valves and how it cranks before and after setting them. I need to get that video put together and posted. Thanks for watching!
