I have a question about grounding with a pwm unit. Can I run positive wire to control side and a short ground to chassis. Then can I run positive power to the motor and short ground to chassis at both the pwm and motor? Or will I have to run a full circuit +/- between pwm and motor. I also want to install an amp meter there, normally it would be on the negative between pwm and motor. Can I install the meter on the pwm's short ground if it's possible to do it that way?
PWM and a variable controllable duty cycle does not necessarily have to be computer controlled or associated with a computer. You are incorrect on that point. You can create a multivibrator with adjustable frequency and duty cycle using a 555 time chip without the use of any digital electronics or computer.
Thank you for your input. You are right on this matter. I am not familiar with circuit design. Here i tried to explain automotive diagnostics on PWM. In the automotive system mostly PWM generate in a controller module. Because it consider input Data and process them to output right duty cycle.

Amazing, please keep up the good work.
Thank you. Your time and skills are appreciated
Thank you.
amazing how the scope works with the Hscope software
That is awesome!

You can do it.
Which oscilloscope is best for automobile sir ?
