Correct Answer
C. Main Switch
Explanation
The main switch is the component that functions as the main power switch for both the charging system and the ignition system. It is responsible for controlling the flow of electricity to these systems, allowing them to be turned on or off as needed. Without the main switch, the entire electrical system of the vehicle would not be able to function properly.

Dalam rangkaian kelistrikan, ada sebuah komponen yang tugasnya menyalurkan arus listrik mengalir ke arah yang berlawanan jika tegangan yang diberikan melampaui batas. Komponen apakah itu ?
Correct Answer
D. Diode Zener
Explanation
A diode Zener is a component in an electrical circuit that allows the flow of current in the opposite direction when the applied voltage exceeds a certain limit. It is used to regulate or stabilize voltage levels in a circuit. When the voltage reaches the Zener voltage, the diode conducts in the reverse direction, preventing any further increase in voltage. This characteristic makes it useful for protecting sensitive components from voltage spikes or for voltage regulation purposes.

Komponen nomor berapakah yang harus diperiksa apabila nyala api pada busi berwarna merah dan letupannya kecil ...
Correct Answer
D. 4, 5, dan 6
Explanation
The correct answer is 4, 5, and 6. When the spark plug produces a small spark and has a red color, it indicates a weak ignition system. The components that should be checked in this situation are the CDI (number 4), ignition coil (number 5), and spark plug (number 6). These components are crucial in generating a strong spark to ignite the fuel-air mixture in the engine. By inspecting and potentially replacing these components, the ignition system can be restored to its optimal performance.

Apakah yang dimaksud langkah " kalibrasi " pada pengukuran menggunakan AVOmeter ...
Correct Answer
A. Langkah menentukan kembali titik 0 pada skala pengukuran
Explanation
The correct answer is "Langkah menentukan kembali titik 0 pada skala pengukuran" which means "The step of re-determining the zero point on the measurement scale." This step is important in calibration because it ensures that the measurement scale is accurate and aligned properly. By re-establishing the zero point, any potential errors or offsets in the measurement can be corrected, leading to more accurate and reliable measurements.

Dalam pengukuran tegangan baterai, apakah yang harus dilakukan pertama kali ...
Correct Answer
D. Memeriksa kapasitas tegangan dan menyesuaikannya dengan skala ukur tegangan maksimal
Explanation
The first step in measuring battery voltage is to check the voltage capacity and adjust it to the maximum voltage scale. This is important because it ensures that the measurement is within the range of the voltage scale being used. By doing this, accurate and reliable voltage readings can be obtained.
8.
Simbol apakah ini
Correct Answer
A. Baterai 6 sel
Explanation
The correct answer is "Baterai 6 sel." This is because the question asks for the symbol of this item, and "Baterai 6 sel" is the only option that represents a battery with 6 cells. The other options mention different types of batteries but do not specify the number of cells.
9.
Terminal yang menghubungkan CDI dengan Ignition Pulcer dihubungkan oleh kabel berwarna ...
Correct Answer
D. Biru/ Kuning
Explanation
The correct answer is Biru/ Kuning. This is because the question is asking for the color of the cable that connects the CDI (Capacitor Discharge Ignition) with the Ignition Pulcer. The color combination of blue and yellow (Biru/ Kuning) is the correct choice for this connection.
10.
Jarum tidak bergerak pada saat melakukan pengukuran tahanan CDI dari terminal Exiter ke Ignition, itu artinya ...
Correct Answer
D. Tahanan Tidak Terhingga
Explanation
If the needle does not move when measuring the resistance from the Exiter terminal to the Ignition, it means that the resistance is infinite. This could be due to an open circuit or a broken connection in the circuit.
11.
Pada saat pengisian kembali elektrolit baterai, maka yang digunakan adalah cairan ...
Correct Answer
D. Asam Sulfat
Explanation
When refilling the battery electrolyte, sulfuric acid is used. This is because sulfuric acid is commonly used as an electrolyte in batteries due to its high conductivity and ability to react with the battery plates to generate electricity. It is also a strong acid that can dissociate into ions, allowing the flow of electric current in the battery. Using pure water or other acids like carbonic acid or cardiology acid would not be suitable for refilling the battery electrolyte. Therefore, the correct answer is sulfuric acid.

Gambar di samping adalah komponen sistem pengapian yang berfungsi ...
Correct Answer
B. Mengatur timing/ waktu pengapian
Explanation
The correct answer is "Mengatur timing/ waktu pengapian." The picture shown is a component of the ignition system, which is responsible for controlling the timing or ignition timing of the engine. The ignition timing refers to the precise moment when the spark plugs ignite the fuel-air mixture in the combustion chamber. By adjusting the timing, the engine's performance can be optimized, ensuring efficient combustion and maximum power output.
14.
Berapakah skala pengukuran untuk memeriksa koil pengapian dan CDI
Correct Answer
A. X1K
Explanation
The correct answer is x1K. This scale of measurement is used to check the ignition coil and CDI (Capacitor Discharge Ignition) system. The x1K scale allows for a more accurate measurement of the electrical resistance in the coil and CDI, which is important for troubleshooting and diagnosing any issues with the ignition system.

Jarum menunjukkan angka lebih dari 5 dan kurang dari 5.5 DCV pada skala ukur 10 DCV. Maka baterai tersebut haruslah ...
Correct Answer
A. Ditambah sulingan air murni dan dicharge ulang arusnya
Explanation
The needle on the scale indicates a voltage between 5 and 5.5 DCV, which means that the battery is not completely discharged. Adding distilled water and recharging the current would be the appropriate action to take in this situation.
