Hello everyone, I'm new to the field of electronics. I'm currently studying for An associates in engineering. I figure this site will expand my learning experience in the fundamentals. At the moment I am in the middle of an issue. I'm working on a car, and I'm suspecting that it has an issue with good source of ground. Is there any way I can test this out? Will I have to consider the resistance of the car as a whole? Any input will be appreciated thanks..
