Depending on the mower some have belt driven generator . But most have a alternator under the fly wheel . It might also be a faulty rectifier.
Hope this helps.
Mower has a generator, which is turned by the engine. When engine is running, generator produces electricity to charge the storage battery.
Dead cell in battery, loose of corroded battery connections, or the charging system on the mower engine is defective.
the same way a car
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
There is a charging system that is under the flywheel. It is a magnetto system.
Do you mean that you can not charge it with a battery charger or the mower will not charge it while it is running? If you can not charge it with a battery charger and you are sure that the charger works then the battery is bad. These type batteries are only good for a couple years. If the mower is not charging the battery it could be a number of things.
I'm assuming its a riding lawn mower of some type. Our own lawn mowers of this type have an alternator in them that keeps the battery charged
A battery float charger is intended only to keep a fully charged battery from losing its charge. It will NOT work to charge a battery that is discharged or damaged. Check the voltage of the battery to be charged. Do not use charger if the battery voltage is less than 9.6 volts.
Yes, but it takes a very, very long time. The charging system on the riding mower is very low amperage. You would do much better charging it with a battery charger.
I suppose you're referring to a riding mower. As you didn't specify the age, make, etc, this will be an educated guess. If the mower is kept in a controlled environment, such as a garage with heat during the winter months, the battery should hold charge for years. If it is kept in a shed outside, then you'll probably need to charge the mower's battery every spring. All you need is a battery charger with jumper cables. Make sure it is capable of charging you're mower's battery. The battery is charged by a generator or magneto. It is located under the flywheel.
till its charged...put it on slow charge and let it set the night. Here is the big secret on batteries....with both post exposed and not running, just the air afloat in the air will drain the battery, solution....when you are going to store for the winter, pull the battery out, put it in a ice chest, or sealed container so air does not get to it, and I think you will find next season it will still be charged.
With a 10 amp charge about 1 hour if the battery is totally dead. You should really use an automatic battery charger that shuts off when the battery is fully charged to avoid overcharging.
