Question

Technician A says test lights are great for quick tests on non-computerized circuits. Technician B says you can use a test light to check SRS circuits and computer circuits. Who is correct?

Answer 1

In digital circuits the current is very small in the order of milliamps, so there is not enough power to turn on these lights.

From the above it is seen that technician A is right
