The ability to detect, observe, and measure electricity is crucial when trying to understand how a tractor works and learning what you can do to fix it. The digital multi-meter is like a doctor’s stethoscope. It allows us to see the invisible force of electricity and measure how it interacts with the components in our engines and tractors. A digital multi-meter measures current (amps), voltage (volts), and resistance (ohms).
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.
As your engine turns, the camshaft pushes your breaker points open, which creates a high voltage induction in your ignition coil. This high voltage power runs through your spark plug igniting your engine. Residual electricity in your ignition coil’s primary circuit is absorbed by the condenser.
Do you want to turn your old garden tractor into a serious earth moving machine? How about convert your manual lift system into a power system? Want to add a rear PTO? Do you want to multiply your engine’s power by 1,000 times or more? It’s all possible by using the science behind hydraulic power!
