Final answer:
Technician A is correct as connecting a test light in place of a fuse and waiting for it to turn off when disconnecting the problem circuit is a standard method to find a short to ground. Technician B's advice is not standard for this test. Therefore, the correct answer is A) Technician A.
Step-by-step explanation:
The question pertains to the correct procedure for using a test light to find a short to ground in an electrical circuit, typically in automotive applications. Technician A suggests that the test light, when connected in place of a blown fuse, will illuminate if the shorted circuit is disconnected. This method is used to identify which circuit is causing the short by disconnecting different circuits until the test light turns off, indicating that the short has been removed from the system. On the other hand, Technician B states that the test light should be connected directly to the battery's positive (+) and negative (-) terminals. This statement is not typically relevant to finding a short to ground using a test light as the standard diagnostic process involves connecting the test light in series with the circuit, not directly across a power source like a battery. Considering the procedures generally followed in automotive electrical diagnostics, Technician A is correct because connecting a test light in place of a fuse and watching for it to go out when the problem circuit is disconnected is a valid technique to identify a short to ground. Technician B's statement is not standard practice for this testing method. Therefore, the correct answer is A) Technician A.
