Spring is around the corner - so decided to tend on my mower. Last
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
Mower is a Toro with 11HP Brigs.
Battery is brand spanking new.
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?

The output of that regualator is meant to be the same 13.x volts DC,
but the anticipated input is very different. The car it is meant for
has an alternator, but your lawnmower doesn't, does it? (I don't know
much about big lawn mowers. Do they have generators instead of
alternators, or some third thing?)
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
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?
Yeah, it is a coil mounted around the flywheel.
You can go to the B&S Site and get an illustrated parts listing:
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.
