Why is there no power in the car?
1 Answers
Reasons for no power in the car: 1. The battery is aged and scrapped; 2. The car has been parked for too long, causing the battery to lose power; 3. A car circuit failure prevents the battery's power from reaching the entire vehicle; 4. The fuse circuit is burned out or has poor contact. If the entire vehicle has no power, it should be promptly checked and repaired at a maintenance shop. Methods to troubleshoot no power in the car: 1. Choose a suitable current clamp, connect the output end to the diagnostic instrument, and after matching, call up the current detection interface; 2. Confirm the connection direction of the current clamp's positive and negative poles—the current arrow should be consistent with the actual current direction, ensuring the current clamp is fully closed; 3. After confirming the equipment is correctly connected, turn off the vehicle's power and lock it, wait for the vehicle to enter sleep mode, then detect the vehicle's static current. If the static current is too high or fluctuates significantly, it indicates a leakage phenomenon in the vehicle.
