Active ground means that there's a wire connected to the block that also connects to the distributor. As long as the ends of the wire are clean grounds then you have a an active ground.
It should be noted that the active/passive ground issue in the Opel distributor is a known issue that pops up over time. What many don't know is that there's a ground strap INSIDE the distributor that connects the points plate (pertronix also) to the housing of the distributor. This is the active ground component inside the distributor. You can cut that strap (or it wears out) and the engine can display the symptoms Gordon is having.Thanks. It's a gift and a curse.Originally Posted by Scifi Guy
