To test your Onan ignition coil, simply disconnect the positive and negative wires from the coil. Now connect a jumper wire from the batt + to the + coil post, and another to a good ground. Tap the ground jumper on the negative coil post to test if the spark plug will spark. An ignition coil's purpose is to convert the low current from a car battery into sufficient power to … [Read more...] about How to Test Onan Ignition Coil | Step-by-Step Guidance

Squirrel Cage Fan Wiring Diagram | Learn How to Wire Your Fan with Ease!
The squirrel cage fan requires special wiring to function properly. The wiring diagram shows the fan regulator, switch, capacitor, and wire colors. Incoming hot wire, which is the black wire on the cord, is connected to the red wire. The 2nd and 3rd “unused” terminals are connected and tied through the #7 contact and #1 connector, respectively. Once these three are connected, … [Read more...] about Squirrel Cage Fan Wiring Diagram | Learn How to Wire Your Fan with Ease!
How to Reduce Noise in Oscilloscope
The noise of the oscilloscope can be reduced using a bandwidth limit filter, average acquisition mode, math filter ( filter Vu ), and by filling the screen. These are the common three methods. An oscilloscope is an electronic instrument used for testing electrical circuits. It can display two or more signals graphically in a cycle of time. Oscilloscope … [Read more...] about How to Reduce Noise in Oscilloscope
How to Use Oscilloscope to Measure Voltage | A Comprehensive Guide
The most basic technique of measuring voltage is to count the number of divisions a waveform spans on the vertical scale of an oscilloscope. The best voltage measurements are obtained by adjusting the signal to cover the majority of the display vertically. Most oscilloscopes can only monitor voltage directly, not current. The voltage dropped across a shunt resistor is one … [Read more...] about How to Use Oscilloscope to Measure Voltage | A Comprehensive Guide
How to Find Threshold Voltage of a Mosfet From Graph
To determine the threshold voltage, use the equation of the drain current as a function of the gate to source voltage VGS in the VDS saturation region. VDS(sat)=> VGS-Vth defines the saturation region. The transfer curve at drain current saturation is what it is called. Threshold voltage can be defined in a variety of ways for measurement purposes. One common metric is: … [Read more...] about How to Find Threshold Voltage of a Mosfet From Graph
