Determining several conditions of fuse burnout

1. Confirm the battery has electricity but the vehicle cannot start; the fuse of the motor starting the car is very likely to burn out. It is necessary to note that when the vehicle is found to be unable to start, keep in mind not to fire continuously, the continuous spark will cause the battery to continue to discharge up to the embarrassing situation of no electricity.

2. While driving, the vehicle's tachometer displays normally but the speedometer shows zero, and the ABS alarm light turns on, which shows that the fuse corresponding to the ABS burnt out. Some irregular business transport vehicles will unplug the fuse managing the ABS, the purpose is to not increase the mileage, but this brings the very big hidden danger, the loss of ABS will make vehicles very dangerous under an emergency situation.

Attentions in change of fuse

1. Replace the fuse with the same specification

If with small current, the fuse will soon burn, if with large current, then the fuse is not easy to burn in the case of short-circuit, thus it is very easy to cause fire. You should look at the mark of Amp at the top of the fuse when disassembling. If the fuse is burnt out so much so that the ampere value is unrecognizable, we can also use its color to judge, international standards: 2A Gray, 3A Purple, 4A Pink, 5A Orange, 7.5A Brown, 10A Red, 15A Blue, 20A Yellow, 25A Colorless transparent, 30A Green, 40A Deep orange color.

2. Take the right seats

There are a lot of fuses in the fuse box. The car has a lot of circuits available for the selectable equipments, so there are many empty positions in the fuse box accordingly, if the fuse is inserted in the vacancy, it will not play a role. You should carefully check the appliances marked in English on the fuse box before the installation. Thus the fuse can play the best and most critical role.
