Vehicles equipped with diesel engines may have two batteries connected in parallel in order to provide additional current at the same voltage. Technician A says to successfully test the batteries, they should be disconnected and tested separately. Technician B says that a fault in one battery has NO effect on the other battery. Who is right?
◦ Technician A only
◦ Technician B only
◦ Both technicians A and B
◦ Neither technician A nor B
