Technician A says that when back-probing an electrical connector with a T-pin, it is permissible to poke the T-pin through the wire as long as you do it carefully. Technician B says that it is permissible to back-probe an electrical connector on a 42-volt system as well as on a 14-volt system. Who is correct?
A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Question

Quizplus · Accepted Answer

Poking a T-pin through a wire can damage the wire's insulation, leading to potential shorts or corrosion issues. Back-probing should be done carefully to avoid such damage. Regarding voltage systems, the technique of back-probing does not inherently depend on the system's voltage but rather on the correct procedure and tools used, ensuring they are rated for the specific voltage. However, the statement from Technician B does not address the precautions or correct procedures, making it insufficient to deem it correct without further context on safety and appropriate tools.
