What are the reasons for the complete power loss in a Haval H6?

The reasons for the complete power loss in a Haval H6 are: 1. When the car's alternator malfunctions, it cannot properly supply power to all the vehicle's electrical components, nor can it charge the battery; 2. Electrical circuit issues, such as grounding of the body wiring harness or unauthorized modifications to the wiring that cause excessive current and burn out the wires. Taking the 2019 Haval H6 as an example, its body structure is a 5-door, 5-seat SUV with dimensions of 4600mm in length, 1860mm in width, and 1720mm in height, a wheelbase of 2680mm, a fuel tank capacity of 58 liters, a trunk capacity of 808 liters, and a body weight of 1625kg.
My Haval H6 had a complete power failure last time, and after struggling for a while, I found out the battery was completely dead. The car was parked on the roadside, and turning the key gave no response at all—not even the dashboard lit up. There are quite a few common reasons for this, such as the battery reaching the end of its lifespan or loose/corroded terminals preventing power transmission. It could also be a faulty alternator, leading to insufficient charging and the battery draining over time. I tried checking the fuses and replacing them, but it didn’t help. Later, after towing it to the shop for repairs, the issue turned out to be with the negative cable. So, it’s good practice to check the battery’s health every six months or pay attention to whether the interior lights dim while driving—spotting problems early saves hassle. Also, the Haval H6 is well-designed but has many electronic systems, so remember to turn off all devices when parked to avoid battery drain. If it happens, don’t panic—first pull over safely and then seek help.
When encountering a complete power failure in the car, I tried some basic troubleshooting myself: First, open the hood to check if the battery terminals are loose—a common issue with older Haval H6 models. Next, inspect the fuse box, located on the driver's side, and check each fuse one by one to see if any are blown. If the fuses are intact, the problem might be a faulty alternator not charging the battery, leading to gradual power loss. In this case, use a multimeter to measure the voltage; it should normally be around 12 volts—if it's lower, the battery likely needs replacement. Once, I even encountered a short circuit in the anti-theft system that locked the circuit, which resolved after a restart, but most cases require professional repair. DIY car repairs require caution to avoid short circuits and injuries. It's advisable to keep a portable jump starter for emergencies. The Haval H6 is a sturdy model, but its wiring tends to age faster, so remind your mechanic to check this critical point during regular maintenance to prevent issues.
