1.
What can the battery do?
Correct Answer(s)
A. Stabalize voltage
C. Turn chemical energy to electrical energy
Explanation
The battery can stabilize voltage by providing a constant and steady flow of electrical energy. Additionally, it can turn chemical energy into electrical energy, as it converts the stored chemical energy into usable electrical energy.
2.
The starter manually activates with what entered?
Correct Answer
D. Car key
Explanation
The starter in a car is manually activated by using a car key. When the key is inserted into the ignition and turned, it sends an electrical signal to the starter motor, which then engages and starts the engine. The other options listed, such as positive and negative cables, neighbor's dog food, and jumper cables, do not have any connection to the activation of the car starter.
3.
What does the Solenoid give access to in a car?
Correct Answer
Power
Control
Explanation
The solenoid in a car gives access to both power and control. It is an electromechanical device that converts electrical energy into mechanical movement. The solenoid is responsible for controlling various systems in the car, such as the starter motor, fuel injectors, and transmission. It allows power to be delivered to these systems and also provides control over their operation.
4.
The starter relies on the alternator.
Correct Answer
B. False
Explanation
The statement "The starter relies on the alternator" is false. The starter is a device used to start the engine, typically by engaging the flywheel to crank the engine. The alternator, on the other hand, is responsible for charging the battery and providing electrical power to the vehicle's electrical system. While both the starter and alternator are important components of a vehicle's electrical system, they serve different functions and do not rely on each other for operation.
5.
Does Lithium Grease prevent Chemical or Electrical damage?
Correct Answer
B. Chemical
Explanation
Lithium grease is primarily used as a lubricant to reduce friction and protect against wear and tear. While it can provide some level of protection against chemical damage, it is not specifically designed to prevent it. On the other hand, when it comes to electrical damage, lithium grease does not offer any protection or insulation. Therefore, the correct answer is Chemical.
6.
What do you clean after removing the car battery when replacing it?
Correct Answer(s)
B. Terminal clamps
C. The battery tray
Explanation
After removing the car battery when replacing it, it is important to clean the terminal clamps and the battery tray. The terminal clamps can accumulate dirt, corrosion, and debris over time, which can affect the battery's performance. Cleaning the terminal clamps ensures a good connection between the battery and the car's electrical system. Additionally, the battery tray may also have dirt and debris that needs to be cleaned to prevent any damage or interference with the new battery. Cleaning these components helps maintain the car's electrical system and ensures proper functioning of the new battery.
7.
When replacing the starter, which cable do you disconnect first?
Correct Answer
B. Negative
Explanation
When replacing the starter, it is important to disconnect the negative cable first. This is because the negative cable is connected to the ground and removing it first ensures that there is no electrical current flowing through the system, reducing the risk of electrical shock or damage to the components. Disconnecting the positive cable first could still leave the negative cable connected to the ground and create a potential for electrical current to flow.
8.
How many alternator retaining bolts are there?
Correct Answer
A. Two
Explanation
The correct answer is Two because an alternator typically has two retaining bolts that secure it in place. These bolts are used to hold the alternator firmly to the mounting bracket, ensuring that it stays in position while the engine is running. Having two bolts provides stability and prevents any movement or vibration that could potentially damage the alternator or its components.
9.
When charging the car battery, what do you remove first?
Correct Answer
D. Battery caps
Explanation
When charging a car battery, it is important to remove the battery caps first. This is because the battery caps provide access to the individual cells of the battery, and removing them allows for proper ventilation during the charging process. Additionally, removing the battery caps prevents any potential buildup of gases or pressure within the battery, reducing the risk of an explosion or other safety hazards. Therefore, removing the battery caps is the first step to ensure a safe and effective charging process.
10.
When replacing a car battery, what should you make sure to do with the terminals?
Correct Answer(s)
B. Disconnect the positive terminal
D. Disconnect the negative terminal
Explanation
When replacing a car battery, it is important to disconnect the positive terminal first. This is because the positive terminal is usually connected to the electrical system of the car, and disconnecting it first helps to prevent any accidental short circuits or sparks. After disconnecting the positive terminal, the negative terminal should be disconnected next. This sequence ensures that the electrical system is safely disconnected before removing the battery.
