Circuit

There are many reasons why the drill can't hit the car, and the most common reason for the failure to hit the car is the circuit. So how to judge that it is the circuit that causes the car to be unable to hit the car?

The failure to start the car due to a circuit failure is mainly manifested in the fact that there is no response when turning on the ignition switch or the starting motor speed is too low, and you can feel a sense of weakness. If these two phenomena can't hit the car, it can be roughly judged as a fault in the starting circuit. Then, how to troubleshoot it?

Check the battery pile head

Checking the circuit can start from the source. First, check the battery pile head, clean the battery pile head, and then tighten the screw of the pile head. The editor used to be unable to drive the car several times because the battery pile head was loose, resulting in poor contact. , The voltage is not enough. If possible, the owner can use a multimeter to measure the battery voltage.

If there is no fault in the battery, the next step is to check the circuit. Check the circuit along the battery to see if there is a broken circuit or a loose connector.

Check the relay box and fuse box

Next, start to check the starting relay and fuse box, open the relay box to check whether the connector is loose, and then open the fuse box to check whether the fuse of the starting circuit is burned out.

Of course, the starter motor or generator failure can also cause the car to fail. Among them, the generator failure will cause the generator to not generate power normally, and the battery power cannot be replenished, resulting in a low speed or no rotation of the starter motor.
