How often must insulated lineman's gloves be tested and recertified?

List five commonsense rules that should be followed when working on a hybrid vehicle.

Technician A says most hybrids also have an auxiliary 12-volt battery to power conventional electrical items, such as lighting, wipers, sound systems, etc. Technician B says the DC-DC converter reduces some of the high voltage DC from the battery pack to 12-volt DC in order to charge the auxiliary 12-volt battery. Who is correct?

Which of the following is NOT true concerning the Power-Split System currently used on Ford, Nissan, and Toyota hybrid vehicles?

The Hyundai Sonata Hybrid uses BAS and ISAD systems.

What equipment is needed to safely test the high-voltage components of the hybrid vehicle electrical system?

Any vehicle that combines two or more sources of power is called a ___________________.

Hybrid vehicles are being discussed. Technician A says in a series hybrid the engine is there only to extend the vehicle's driving range. Technician B says in a parallel hybrid the electric motor and batteries are the main power source during normal driving conditions. Who is correct?

Technician A says an insulation resistance tester measures voltage. Technician B says an insulation resistance tester measures the effectiveness of a wire's insulation. Who is correct?

Which of the following is NOT an advantage of a hybrid vehicle?

The ________________system replaces the traditional starter and generator in a conventional vehicle and is connected to the engine's crankshaft by a drive belt.

What is the purpose of a typical inverter?

When working on a high-voltage system, it is best to keep anyone who is not part of the service away from you and the car by creating a buffer zone around the car.
