The engines in our beloved garden tractors have enough power to push hydraulic oil to 2,000 psi or more. By pushing this oil into different sized hydraulic cylinders we can build almost any tool imaginable.
To measure AC voltage for example on your engine’s stator, you first locate the two wires coming from the stator. Turn your DMM to AC Voltage. Place the red probe onto one of the wires, and the black probe on the other wire. You should read about 24 to 30 VAC.
The 3 Most basic principles behind hydraulics are:1.) Liquids are incompressible2.) Liquids transmit pressure in all directions and with equal force at right angles to all surfaces3.) Liquids under pressure follow the path of least resistance
To measure voltage on a battery for example you first turn your meter to DC Voltage. Place the red probe on the positive terminal of the battery and place the black probe on the negative side of the battery or on a common ground. Your voltage will display on the screen.
