With the use of high pressure injectors it takes a 100V pulse to actually fire the injector. There is also some back EMF from the solenoids as the pulse ends and the solenoid opens. Unfortunately the

If you've arranged for local hams to cover every active and imminently active BPL pilot, then my criticism was indeed incorrect. Is there a similar effort aimed at hams working for public service age
