Technician B says that the correct specification is 9.6 volts during cranking; therefore, the starter, battery, or cables are defective. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 2. The charging system voltage is found to be lower than specified by the vehicle manufacturer. Technician A says that a loose or defective drive belt could be the cause. Technician B says that a defective alternator could be the cause. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 3. Battery voltage during cranking is below specifications. Technician A says that the engine may be the cause. Technician B says that the starter motor may be defective. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 4. Two technicians are discussing distributorless (EI) ignition. Technician A says that the crankshaft sensor triggers the module. Technician B says that the module controls the primary circuit of the ignition coil. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 5. An engine cranks but will not start. No spark is available at the end of a spark plug wire with a spark tester connected and the engine cranked. Technician A says that a defective pickup coil could be the cause. Technician B says that a defective ignition module could be the cause. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 6. Technician A says that coolant flows through the engine passages and does not flow through the radiator until the thermostat opens. Technician B says that the temperature rating of the thermostat indicates the temperature of the coolant when the thermostat is opened fully. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 7. Technician A says the higher the concentration of antifreeze, the better the cooling. Technician B says that a 50/50 mix of antifreeze and water is the ratio recommended by most vehicle manufacturers. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 8. Technician A says that if the thermostat is removed from the engine, the engine may overheat. Technician B says that coolant bypasses the thermostat when the thermostat is closed on some engines. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 9. Technician A says that the radiator pressure cap is designed to raise the boiling point of the coolant. Technician B says that the radiator pressure cap is designed to lower the boiling point of the coolant. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B 10. Technician A says that used antifreeze coolant is not considered to be hazardous waste. Technician B says that metals absorbed by the coolant when it is used in an engine make antifreeze less harmful. Which technician is correct? a) Technician A only b) Technician B only c) Both Technician A and B d) Neither Technician A nor B Go to top of quiz © 2004 Prentice Hall. All Rights Reserved.
