2.9.1 Classification of fuses
The plug-in fuse can be divided into: super trivial fuse, small car fuse, medium car fuse, large car fuse .
The rated current is from 1 to 40A to large 30 ~ 120A, and the rated voltage is 32V.

2.9.2 How to view car fuse damage
(1) Method 1
① Insert the key and power the vehicle.
② Remove the insurance box and clip.
③ Use the clip of the test lamp to hold the iron office on the car.
④ Use the fuse of the test light to light up, the fuse is good, the fuse is good, the test light is not light, it is damage to the fuse .
Find the fuse
(2) Method 2
Open the multimeter to the gear of the measuring line. One point is on the fuse, and the other is on the other end of the fuse. The sound of the multimeter drip is to power, indicating that the fuse is good. Essence
(3) Method three
Observation of the naked eye, the fuse is broken in the middle of the fuse, and the fuse is burned out, and the fuse is good.
2.9.3 Skills and use of car fuse replacement
① If there is no spare fuse, you can use other idle fuse tops. For example, the fuse of the car window is broken, and there is no spare fuse. At this time, you can use the idle fuses such as audio and air conditioners, provided that the rated current of the two is the same or higher than the original fuse.
② Put a high -power car light. After changing the headlights, the power is too large, it is easy to melt the fuse. The large current fuse and power cord should be replaced in time to prevent the current from being overheated.
③ Modify high -power audio. Ultra -power audio also melts the fuse. When installing high -power electrical appliances, you must pay attention to the size of the electrical current and replace the corresponding fuse in time. Generally, good modification stores will pay attention to such problems.
④ Rinse the engine compartment with water. When cleaning the engine compartment, because the fuse box is not very appropriate, remember not to rinse the fuse box directly with water, otherwise it will easily lead to short circuits of the fuse and cause the vehicle's electrical components to fail. Most fuse boxes have obviously prohibited icons rinse with water. If the fuse box is dirty, gently scrub with a wet towel.
⑤ Cigarette lighter for high -power appliances. The cigarette fuse is easy to melt. The general cigarette lighter uses a fuse of 15 to 25A. Because the vehicle voltage is 12V, the electrical appliances are recommended by the cigarette lighter for no more than 300W, and some small cars do not exceed 200W. As for high -power electrical appliances such as vehicle refrigerators and vehicle inflatable pumps, use less electrical appliances.
