Two technicians are discussing a fuel gauge on a General motors vehicle. Technician A says that if the ground wire connection to fuel tank sending unit becomes rusty or corroded, the fuel gauge will read higher than normal. Technician B says that when the power lead to the fuel tank sending unit is disconnected from the tank unit and grounded (ignition on), the fuel gauge should go to empty. Who is right?
◦ Technician A only
◦ Technician B only
◦ Both technicians A and B
◦ Neither technician A nor B
