A voltmeter was used to check the coolant and a reading of 0.2 volt with the engine off was measured. A reading of 0.8 volt was measured with the engine running and all electrical accessories turned on. Technician A says that the coolant should be flushed to solve the galvanic activity. Technician B says that the ground wires and connections should be inspected and repaired to solve the electrolysis problem. Which technician is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A and B

Respuesta :

Answer:

B) Technician B only.

Explanation:

Coolant is a liquid used to keep the temperature of the engine of the under control.When checked the voltage readings it gives 0.2V when the engine is off and 0.8V when the engine running and all electrical accessories turned on.Technician B is right as he suggested that the connection of ground wires is not proper hence it should be inspected and repaired so that this problem of electrolysis can be solved.
