Lawn mower problem - possibly electrical
Spring is around the corner - so decided to tend on my mower. Last
mowing season, a branch got stuck and burnt a wire. I replaced the wire, the voltage regulator. The mower starts and runs for about 20 minutes, before dying on me. Then it will not start up because the battery goes dead. I charge up the battery, mower starts up pretty good - runs for 20 mins and battery is dead !! First question is, does these mowers have charging system? Does it seem like the charging system is bad? Or do you think there is an electrical short? If I need to look for a short, where should I start? Mower is a Toro with 11HP Brigs. Battery is brand spanking new. |

You say you replaced the regulator, well that controls charge. Start
there with a volt meter. |

Ok. From what I gather from the reply so far, it is not a short. It
seems the charging system is broke somewhere. I replaced the regulator with an automotive one, as I could not find a lawn mower one handy. I will start there again to check. I am looking for information on the charging system of a Briggs and Stratton (I do not know if it will be any different when installed on a Toro). I do not know if getting one of the Briggs repair manual will help me on that. Can you guys point me to the right direction? |

You put a Automobile voltage regulator on a Briggs & Stratton and are
here asking why the battery is dead! Start with the right regulator, im sure you will be happy. |

In the words of Bart Simpson, Aye Karoomba! Even he wouldn't be dumb enough to do this. What's next, putting the blade on the car? |

Now guys ! Go easy on me ! I am not a professional and I accept my
mistake (if it is indeed one). I thought that a 12V regulator is a 12V regulator and so should not make a difference. I will get a proper regulator and try it on. Will post back with results. |

Will post back with results. off the top of my head, it doesn't sound like a completely impossible idea... i haven't seen a separate regulator on a car in a long time. where did you get it? maybe it's dead? |

Without a engine model # I can't say with 100% certainty, but most Briggs do have a diode in the charging circuit to prevent the battery from discharging back through the alternator. MikeB |

It has a rotor -stater , no generator- alternator right, start with
seeing if it is outputting electricity. and what V. |

I got the regulator from Autozone. Suppose to be for an older GM car.
Also, where is the charging system on a Briggs? Is it in-built - like in the flywheel? Where would be the diode that you are talking about? |

The B&S in that range ive seen have no generator just a rotor and
stator, which might be the real issue. I might guess the car regulator could have to high a minimum amp input need and not open. |

Where would be the diode that you are talking about? Yeah, it is a coil mounted around the flywheel. You can go to the B&S Site and get an illustrated parts listing: http://www.briggsandstratton.com/dis...sp?DocID=64103 If you have your engine number. (It will read something like 234432-0235). That model, engine type number will probably give you and idea of what you are looking at. Click on Owners Manual - Parts list Under Illustrated Parts list click on "Engine IPL" In the left hand column click on "Engine IPLs" Now enter the Model number (such as the 234432 above) and then the Engine type (such as the 0235 above). Then you should have an option of downloading a IPL Form into a PDF file. |
