Technician A is correct because in a waste spark ignition system, coils are often mounted directly on top of the spark plugs, eliminating the need for secondary wires. This is known as coil-on-plug (COP) ignition. Technician B is incorrect because the waste spark system's design typically does not use secondary wires to deliver the ignition spark when coils are mounted directly on the spark plugs.
