Correct Answer
C. Main SwitchExplanation
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.Rate this question:

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 ?
- A.
Main Fuse
- B.
Main Switch
- C.
Main Board
- D.
Diode Zener
- E.
Main Flows
Correct Answer
D. Diode ZenerExplanation
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.Rate this question:

4, 5, dan 6
- E.
Semua Salah
Correct Answer
D. 4, 5, dan 6Explanation
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.Rate this question:

Apakah yang dimaksud langkah " kalibrasi " pada pengukuran menggunakan AVOmeter ...
- A.
Langkah menentukan kembali titik 0 pada skala pengukuran
- B.
Langkah mengalikan skala dengan garis hasil pengukuran
- C.
Memutar selektor ke posisi skala pengukuran
- D.
Memposisikan alat pengukuran
- E.
Menyatakan bahwa pengukuran telah selesai
Correct Answer
A. Langkah menentukan kembali titik 0 pada skala pengukuranExplanation
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.Rate this question:

Dalam pengukuran tegangan baterai, apakah yang harus dilakukan pertama kali ...
- A.
Menentukan objek pengukuran
- B.
Memeriksa kondisi fisik objek pengukuran
- C.
Memastikan skala ukur
- D.
Memeriksa kapasitas tegangan dan menyesuaikannya dengan skala ukur tegangan maksimal
- E.
Memeriksa kutub dan komponen
- F.
Semua salah
Correct Answer
D. Memeriksa kapasitas tegangan dan menyesuaikannya dengan skala ukur tegangan maksimalExplanation
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.Rate this question:

Simbol apakah ini
- A.
Baterai 6 sel
- B.
Baterai Kering
- C.
Baterai Basah
- D.
Baterai Alkali
- E.
Semua salah
Correct Answer
A. Baterai 6 selExplanation
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.Rate this question:

Terminal yang menghubungkan CDI dengan Ignition Pulcer dihubungkan oleh kabel berwarna ...
- A.
Hitam/ Putih
- B.
Hitam/ Merah
- C.
Biru/ Hitam
- D.
Biru/ Kuning
- E.
Hitam/ Kuning
Correct Answer
D. Biru/ KuningExplanation
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.Rate this question:

Jarum tidak bergerak pada saat melakukan pengukuran tahanan CDI dari terminal Exiter ke Ignition, itu artinya ...
- A.
Skala Pengukuran Terlalu Kecil
- B.
Skala Pengukuran Terlalu Besar
- C.
Hasil Pengukuran Tidak Teratur
- D.
Tahanan Tidak Terhingga
- E.
Cara pengukuran salah
Correct Answer
D. Tahanan Tidak TerhinggaExplanation
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.Rate this question:

Pada saat pengisian kembali elektrolit baterai, maka yang digunakan adalah cairan ...
- A.
Sulingan air murni
- B.
Cairan Asam Karbon
- C.
Cairan Asam Kardiologi
- D.
Asam Sulfat
- E.
Semua Benar
Correct Answer
D. Asam SulfatExplanation
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.Rate this question:

- D.
Mengoptimalkan perform kendaraan
- E.
Menurunkan arus manakala terjadi korsleting
Correct Answer
B. Mengatur timing/ waktu pengapianExplanation
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.Rate this question:
