How is it that there is continuity and a voltage reading?
Having the breaker closed means it is acting like a switch that is turned on. Checking from one side of it to the other will naturally show continuity. One verifies the state of a breaker by looking for voltage between the hot lead and its associated neutral.
What does the negative sign of a voltage mean?
The negative sign of the voltage or potential difference represents the loss in potential due to the resistor. The electrical potential difference of different points in the circuit can be represented with the help of a diagram called the electric potential diagram that is shown below.
What causes a generator to have a low voltage?
The capacitor has two functions; it induces voltage into the rotor as well as regulates voltage. A bad capacity will result in a low voltage reading from the generator as the power being generated will be from the residual magnetism of the rotor (usually about 2-5V).
Where are the PWM and 0V voltages located?
The drive signal is normally a pulse width modulated (PWM) square wave (12v & 0v), where the duty determines the average voltage to the motor. It is just possible that 0v will be on terminal 2, and the PWM signal will be on terminal 3. The signal wire is possibly more informative.
What is the voltage of an alternating current fan?
An alternating current fan will have a voltage rating above 100 such as 110V or 240V. In contrast, a direct current fan will have a lower voltage rating such as 5V or 48V.
Why does a fan run at 110V or 120V?
This is because fans are designed to tolerate a range of voltages. So a fan might state 110V on its label but it will be able to run on a 120V power source. The speed of the fan can also by controlled by reducing the voltage input. However, voltages above the fans range could damage it.
What should the voltage be without main relay?
Today I did a test where I measured voltage on Sensor Harness’es Orange wire with and without “main relay” plugged in when key was in “ON”, position: As can be seen the voltage without relay is 2.4V, which I think is wrong. It should have been 0V. My questions are: Based on this test, can I conclude that “main relay” most likely is actually OK?
