So no one though to make the point that if the poster does not know what a multimeter is, does , or how one works; they shouldn't be toutching any car's wiring?

Not to mention that they mentioned it as frustrating the heck out of them?

Think about it guys.

You sir, for you and your car's own good, should have someone experienced and knowledgable about such things working on the wiring.

There's the answer to your question.
