The reason why the water well drilling rig cannot catch fire when starting up

1、 Circuit reason: it is mainly manifested in that there is no response when turning on the ignition switch or the starting motor speed is too low, and it can feel weak. If these two phenomena occur and the car fails to start, it can be roughly determined that the starting circuit has failed.

1. Check the battery pile head

First, check the battery pile head, clean the battery pile head, and then tighten the screw of the pile head. Several times before, the battery pile head failed to catch fire because the battery pile head was loose, resulting in poor contact and insufficient voltage. If possible, the owner can measure the battery voltage with the multi-meter voltage gear. If the battery is not faulty, the next step is to check the line. Follow the line of the battery and observe whether there is a broken line or a loose connector.

2. Check the relay box 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 burnt out. Of course, the failure of the starting motor or generator can also lead to non ignition. Among them, the failure of the generator will lead to the failure of the generator to generate electricity normally, and the battery power cannot be replenished, resulting in the low speed or non rotation of the starting motor.
