What charges the battery on a Briggs and Stratton engine?
The Briggs and Stratton engine uses an alternator to charge the battery. An alternator is an electrical generator that converts mechanical energy into electrical energy. To charge the battery, the alternator uses an electromagnetic field to generate an alternating current (AC) in its windings.
The alternating current passes through a rectifier, which converts it to direct current (DC). This direct current is then delivered to the battery, where it stored until it is needed to start the engine.
The alternator also keeps the battery charged while the engine is running.
Does a riding mower have an alternator?
Yes, a riding mower typically has an alternator. An alternator is an important component of a riding mower’s electrical system and its purpose is to keep the battery charged and the mower’s electrical systems running.
