When something is wired “in parallel” it means it is wired alongside a circuit with its own positive wire. Now that we have a basic idea of electrical theory, let’s examine how it is all wired together. The example below illustrates wiring for an engine that uses battery ignition and a stator charging system.
In order to turn a shaft with combustion, we need to convert not only chemical energy, but we need to convert a reciprocating motion into a rotational motion. The reciprocating motion is the engine’s piston moving up and down, and the rotational motion is the crankshaft turning. As you can imagine there is a lot of things moving all at once with drastic changes in direction and speed. This process generates a lot of unwanted vibration and movement as a by-product.
Measuring voltage is one of the most common tests a tractor mechanic will conduct as he troubleshoots a system. The presence of the correct voltage will determine if a component is functioning correctly or not. A common voltage test will be of the battery. A healthy battery should read about 12.5 volts, and a battery that is being charged should measure between 13 and 14.5 volts.
The hydraulic system begins with the reservoir. This reservoir contains the oil used in the system. Oil is delivered from the reservoir to the hydraulic pump. From there the oil flows to the hydraulic control valve. Once activated, the valve will allow oil to flow to and from the hydraulic cylinder. At the same time, oil is moved from the cylinder back to the reservoir where the cycle repeats.
