Example #1 - Voltage Controlled Driver

These two known-good waveform patterns are from a Ford 4.6L V8 VIN [W]. Fig. Fig 1 illustrates the 64 volt inductive kick on this engine, indicating no clamping is occurring. The second pattern, Fig. Fig 2, was taken during hot idle, closed loop, and no load.
