The charging circuit consists of your battery, ignition switch, rectifier/regulator, and stator. When your engine is operating, your stator produces an alternating current by means of electromagnetic induction. This alternating current is fed to your rectifier/regulator by two wires. These two stator wires connect to the AC – and AC + terminals on the rectifier/regulator. The rectifier/regulator converts the alternating current into a direct current and is fed out of it through the terminal marked B+. This wire leads to the “rectifier or R” terminal on your ignition switch. This direct current charges your battery.
The reservoir holds the fluid; in the case of our garden tractors, oil. The pump moves oil throughout the entire system. The valve directs oil to different hydraulic cylinders or motors. The Piston or Motor is where the final work is performed. A piston will move loads up and down, and a motor will rotate. All of the components are connected by hydraulic hoses or lines.
