A technician is checking resistance in an engine's spark plugs wires using an ohmmeter. A general rule is to replace a wire if resistance is over:

A Front Wheel Drive (FWD) vehicle with an automatic transaxle has excessive vibration. Technician A says that the vibration could be caused by worn engine/transaxle mounts. Technician B says that the vibration could be caused by a misaligned engine/transaxle subframe. Who is right?

Technician A says that if a wire is getting too hot, it's a sign of higher-than-normal current flowing through. Technician B says the wire would heat up if some of the individual strands are broken inside the wire insulation. Who is right?

Technician A says electrical connectors can be disconnected with the ignition switch ON, as long as the technician is using a ground stop. Technician B says when welding on a vehicle, the technician needs to use a static wrist strip. Who is right?

Technician A says the thermostat maintains maximum engine operating temperature. Technician B says if the engine continuously runs hot, install a cooler thermostat. Who is right?

A vehicle equipped with MacPherson strut suspension is in the repair shop for new tires and alignment. The technician noticed that the vehicle has some play in the lift-side inner-tie rod. What should the technician tell the customer.

An engine is losing coolant, yet has no external leaks. Technician A says to run the engine and see if there is white smoke coming out of the exhaust. Technician B says to find out if the engine's emission system uses a catalytic converter before running the test above. Who is right?

All of the following should be performed during a preliminary transmission check EXCEPT:

A smeary film on the windshield is an indication of:

Technician A says that all power should be redirected from a circuit before testing the circuit with an ammeter. Technician B says that all power should be removed from a circuit before testing the circuit with an ohmmeter. Who is right?

A Rear Wheel Drive (RWD) vehicle with a one-piece driveshaft has excessive driveshaft vibration during low speed acceleration. Which of the following is MOST likely the cause?

The warning light on a vehicle with an anti-lock brake system lights when the vehicle stays on. Which of the following could be the cause?

The driver of a vehicle with hydraulic brakes says the pedal is extremely hard when stopping. Technician A says the problem could be in the power assist system. Technician B says the problem is most likely a weak or broken brake shoe return spring. Who is right

Technician A says that DOT 3 brake fluid has a higher boiling point that DOT 4 brake fluid. Technician B says that DOT 5 brake fluid should not be used in a vehicle with ABS. Who is right?

A vehicle is leaking hydraulic fluid from a brake line. Technician A says a short splice can be used to repair the line. Technician B says if the line has not drained the master cylinder, the system does not need to be bled. Who is right

A vehicle with hydraulic brakes has been diagnosed with contaminated brake fluid. Of the following, what would be the proper procedure in the repair process?

All of these could cause tire wear if not within the manufacturer's specification EXCEPT:

The ball points on a MacPherson strut suspension are being replaced. Technician A says that the coil spring compressor should be installed before the separating control arm and spindle. Technician B says that the wheel alignment should be checked after the ball joints have been replaced. Who is right?

Technician A says that a vehicle with TPMS can be identified by looking for a TPMS indicator on the instrument panel during the Key On Engine Off bulb check. Technician B says that all vehicles with TPMS have metal tire valve stems and this feature can be the identifier. Who is right?

Technician A says maintenance-free batteries have a built-in hydrometer can give you an indication of the battery's overall condition. Technician B says since a maintenance-free battery is sealed, it should be checked using a test light. Who is right?

Technician A says that all vehicles with strut-type front suspension require that the strut is removed to replace the front coil springs. Technician B says that the coil spring should be removed before removal of an SLA front suspension. Who is right?

Technician A says an indirect measurement Tire Pressure Monitoring System (TPMS) uses wheel speed sensors to measure tire pressure. Technician B says a direct measurement TPMS uses tire pressure sensor to measure tire pressure. Who is right?

Tire cupping is MOST likely caused by which of the following?

Which setting on a digital multimeter is used to check resistance?

Voltage drop tests are used to locate:

Technician A says a Digital Graphing Multimeter (GMM) can be used to view electronic wave forms. Technician B says GMMs can be used to display vehicle-specific information displayed on-screen. Who is right?

A vehicle has experienced a charging problem. A tech inspected the charging system, found loose alternator mounting bolts, and tightened them. Afterwards, the vehicle performed OK. Tech A says the problem might have been a slipping belt. Tech B says the problem might have been poor grounding of the alternator. Who is right?

A wiper motor is not operating. However, when the linkage is disconnected, the motor operates OK. Tech A says the problem could be a bad relay. tech B says the problem is MOST likely binding linkage. Who is right?

Tech A says that a test light is a good diagnostic tool for testing general lighting circuits and grounds, but should not be used on solid-state electronic circuits. Tech B says that a self-powered test light is a good diagnostic tool for testing voltage sources. Who is right?

Starting system voltage drop tests are used to locate:

Cooling system pressure is maintained by the use of the:

Tech A says that when checking charging system voltage output, all electrical accessories should be on. Tech B says when checking charging system voltage output, the reading should be around 18 volts. Who is right?

Tech A says that pink colored transmission fluid is evidence of fluid aeration. Tech B says that pink colored transmission fluid is caused by coolant contamination. Who is right?

The driver notices a clear fluid dripping from the underside of his vehicle with the engine running and the A/C on. Tech A says this is refrigerant over flow. Tech B says the dripping will stop after the A/C system is shut off. Who is right?

There is liquid leaking into the passenger compartment from the evaporator. Tech A says a leaking heater core could be the problem. Tech B says a clogged evaporator drain could be the problem. Who is right?

A customer is complaining of insufficient air flow through the vents when the A/C is turned on. Tech A says that the problem could be a clogged cabin air filter. Tech B says the problem could be a short at the blower motor. Who is right?
