The condition of a battery cable end (where it connects to the battery post) is questionable. Technician A says a battery leakage test will determine the quality of the connection. Technician B says a battery terminal voltage drop test can be used to determine the quality of the connection. Who is correct?

Question

Technician B is correct. A battery terminal voltage drop test can be used to determine the quality of the connection. This test is performed by measuring the voltage drop across the cable end and the battery post while the vehicle is running. If the voltage drop exceeds a certain amount, this indicates a poor connection. A leakage test is used to test for other issues, such as a faulty battery.
