Exam 69: Ignition System Components and Operation

Technician A says that the ignition timing cannot be adjusted on waste spark ignition systems. Technician B says that most waste spark systems use a crankshaft position sensor. Which technician is correct?

How many ignition coils should you expect to find on a V6 engine using a waste spark system?

Technician A says that the primary and secondary ignition systems are never connected. Technician B says that the primary and secondary windings are connected in some ignition coils. Which technician is correct?

Technician A looks for engine speed (RPM) when cranking an engine that will not start. Technician B says that a problem in the primary circuit could make the tachometer not work. Which technician is correct?

Waste spark ignition is being discussed. Technician A says it requires more voltage to fire the compression cylinder than the companion cylinder. Technician B says waste spark systems that use compression sensing electronics do not require a camshaft sensor for engine position. Which technician is correct?
