We all have ways to do things. I usually just put a piece of metal against the back of the alternator (center shaft cover) and see if there is a magnetic field being generated. My pocket knife works well for this. That tells you if your alternator is making an electrical field. Second, use the VOM to check for voltage to the battery and see what you are getting. The voltage should be around 13.5 volts or more.
