WebBecause each waveform is a superimposed pattern of two cylinders for a single coil, your scope may show a bright spot about three-quarters of the way up the firing line for the waste spark in the cylinder on the exhaust stroke. Also notice that the coil oscillations for a DIS coil are fewer than for a coil on a distributor-type ignition. WebThe induced voltage is produced by a process called magnetic induction. At the point of ignition, the coil's earth circuit is removed and the magnetic field or flux collapses …
