Technician B says the centrifugal advance weights may be stuck. Who is correct? Technician B only A loose spark plug is likely to cause: Premature ignition coil failure A vehicle with an ignition system triggered by a magnetic pulse generator will not start. Technician A says that the air gap should be checked using a go no-go stainless feeler gauge. Technician B says that the air gap is not adjustable. Who is correct? Both Technicians A and B All of the following are types of electronic ignition systems (EI) except: distributor An engine's initial timing is set at 6 degrees ATDC; the specification is 3 degrees BTDC. Technician A says the timing is overly advanced and must be retarded 9 degrees. Technician B says the timing is overly retarded and must be advanced. Who is correct? Technician B only An ohmmeter placed across the primary terminals of an ignition coil indicates 896 k ohms. Technician A says the coil windings are shorted. Technician B says the coil needs to be replaced. Who is correct? Technician B only In the diagram of the V-6 engine, which color represents cylinder #1? orange Spark plugs are being discussed. Technician A says to remove the plugs when the engine is at normal operating temperature. Technician B says to use a torque wrench to tighten them. Who is correct? Technician B only The dwell section of a primary scope pattern represents: the amount of time that the primary current is turned on Too high of a heat range spark plug will: decrease plug life When diagnosing a no-start condition on a vehicle with no spark, Technician A says that the ignition module should be tested for a digital switching signal. Technician B says the Hall effect CMP sensor should be tested for a digital switching signal. Who is right? Both A and B
