- While checking an A/C compressor clutch coil clamping diode with a DMM, the meter shows infinite resistance when the diode is measured in both directions: Technician A says that the diode is open. Technician B says that all diodes should behave this way until a specified voltage is applied to them. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardWhich of the following statements about the SRS warning lamp is not true? When the ignition is first turned on, the indicator should turn on and remain on for approximately 6 seconds. If the system seems to be able to work correctly, the lamp will stay lit as the engine runs. If the lamp flashes or turns off and then turns on again, low source voltage may be indicated. A system problem is indicated when the lamp does not turn on when the ignition is initially turned on.arrow_forwardTechnician A says that based on current conditions, a reference voltage sensor modifies a fixed voltage from the computer and sends that voltage back to the computer. Technician B says that most reference voltage sensors are variable resistors or potentiometers. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
