Gentlemen,

What a week it's been. I purchased a new ignition coil and amplifier for my 1989 3.0 l mercruiser, (they're not cheap), and still no spark. So I removed the wiring harness so see if there is a short or anything. Will a continuity test work to make sure they are fine, or does it need to be hooked up to a battery to really know?
