Final answer:
A multiple cylinder misfire can be caused by a defective coil on a waste spark system, and a low resistance in the primary circuit can reduce secondary circuit kV output.
Step-by-step explanation:
Technician A is correct. A multiple cylinder misfire can be caused by a defective coil on a waste spark system.
In a waste spark system, each cylinder has a pair of spark plugs - one for the compression stroke and one for the exhaust stroke.
The coil produces a spark on both plugs simultaneously. If the coil is defective, it can cause a misfire in multiple cylinders.
Technician B is also correct. A low resistance in the primary circuit can reduce the secondary circuit kV (kilovolts) output.
The primary circuit includes the ignition module, ignition switch, ignition coil primary winding, and the wiring connecting them.
If there is low resistance in this circuit, it can affect the performance of the coil and subsequently reduce the kV output in the secondary circuit.
Therefore, the correct answer is that both Technician A and Technician B are correct in this case.
