Question

1. a battery terminal has a voltage drop of 0.64 v during a cranking test. technician a says the battery should be replaced. technician b says the battery connections should be cleaned and retested. who is correct? technician a technician b both technician a and technician b neither technician a nor technician b

Explanation:

Step1: Analyze voltage - drop value

A voltage drop of 0.64 V during a cranking test is relatively high. However, before replacing the battery, it is good practice to first check and clean the battery connections as a dirty or loose connection can cause high voltage drops.

Step2: Evaluate technician statements

Technician A wants to replace the battery immediately which may be premature. Technician B's suggestion of cleaning and retesting the battery connections is a logical first - step troubleshooting measure.

Answer:

Technician B
