While discussing an ignition problem displayed on a scope primary ignition pattern, Technician A says a worn distributor drive gear can cause an erratic transistor ON signal. Technician B says if there are erratic voltage spikes at the transistor ON signal, the ignition module may be faulty. Who is correct?
A)A only
B)B only
C)both A and B
D)neither A nor B

Question

Quizplus · Accepted Answer

Both technicians are correct. A worn distributor drive gear can indeed cause erratic signals due to inconsistent timing, affecting the transistor ON signal. Similarly, erratic voltage spikes at the transistor ON signal can indicate a fault in the ignition module, as it is responsible for controlling the timing and strength of the ignition spark.
