Both Technician A and B are correct in these statements'
How to analyze the statements
Technician A is correct in stating that the regulated voltage should ideally fall within the manufacturer's specified minimum and maximum voltage range.
This range ensures that the electrical system is operating at the optimal voltage level as intended by the manufacturer.
Technician B is also correct in highlighting the importance of verifying voltage drops on the alternator and regulator wires/cables if the regulated voltage is incorrect.
Voltage drops along these wires/cables can lead to an incorrect output from the charging system, affecting the overall electrical performance.
