OK, I'm ready to lose it! I hate electrical problems!

While driving, my dash gauge is reading <8. The alternator is an internally regulated unit. While doing voltmeter testing, should I have the engine running or not? I'm lost.

Thanx for the replies received so far.

P.S. When trying to fix electrical problems, is it normal to have feelings of wanting to yank out the wiring harness and do a tribal yell at the top of my lungs.
