The car relay is broken. The relay is an important part of the car. If the starter relay is broken, the car will not start. If the ignition switch relay is broken, the car will not start, and if the power window relay is broken, the power window of the car will not be able to rise and fall. There are multiple relays in the car to control multiple circuits. To deal with the problem, we must prescribe the right medicine. Let's take a look at the symptoms of broken car relays.
The car relay is broken, there will be the following conditions:
1. The starting system circuit is faulty. There is an open circuit, poor contact or loose wire in the starting circuit;
2. Power failure, battery power loss or short circuit of pole plate vulcanization, poor contact of starting power wire connection, etc.;
3. Starter failure. The commutator is in poor contact with the brushes, the contact plate and contacts of the electromagnetic switch are in poor contact, and the motor excitation winding or armature winding has a local short circuit.
How to replace the relay:
There are a lot of relays on the car, and a fuse box on the car. A general car has two fuse boxes, one in the engine compartment and the other in the car. After opening the fuse box, you can find that there are many colored fuses in the fuse box, and some black squares, which are actually relays.
If the car’s fuse or relay is damaged, the car may not be able to start the engine, or some electronic equipment may not work. It is very simple to replace the fuse or relay. There are numbers and corresponding functions on the fuse box cover of the car. Just find the corresponding fuse or relay and replace it.
