What is the main cause of frequent fuse damage?
Dec 30,2019
There are always owners who are confused about why fuses always burn, although they usually pay attention to cars. Don't worry, find the real reason first, and then solve it accordingly.
Several conditions for determining fuse breaking
1. Confirm that the battery is powered, but the vehicle cannot be started; the fuse of the motor starting the vehicle is likely to burn out. It should be noted that when the vehicle is found to be unable to start, please remember not to ignite continuously. The continuous spark will cause the battery to continue discharging until there is no power.
2. During driving, the tachometer of the vehicle displays normally, but the tachometer displays as zero, and the ABS alarm light is on, which indicates that the fuse corresponding to the ABS is burnt out. Some irregular business transport vehicles will pull out the fuse of ABS management, in order not to increase mileage, but this brings great hidden danger. The loss of ABS will make the vehicle very dangerous in an emergency.
Pay attention to replace the fuse
1. Replace the fuse of the same specification
If the current is small, the fuse will burn quickly; if the current is large, the fuse is not easy to burn in case of short circuit, so it is easy to cause fire. When removing, pay attention to the amp mark on the top of the fuse. If the fuse burns out so much that the ampere value cannot be recognized, we can also use its color to judge the international standard: 2A gray, 3A purple, 4A pink, 5A orange, 7.5A brown, 10a red, 15A blue, 20A yellow, 25A colorless and transparent, 30A green, 40A dark orange.
2. Take the right seat
There are many fuses in the fuse box. The car has many circuits for optional equipment, so there are many vacancies in the fuse box, if the fuse is inserted into the vacancy, it will not work. Before installation, carefully check the electrical appliances marked in English on the fuse box. Therefore, fuses can play the best and most critical role.
