I'm beginning to understand. Found this: "The period of points closure is typically expressed as degrees of distributor rotation. In a four cylinder engine, the angle between each ignition cam lobe is 90° and the period of points closure or "DWELL" is usually a bit over 45° of distributor rotation."
So you're saying coil heating occurs when the points close (ON). Looks like that's about half the time. When the points close, does the current flow through the coil to ground?
