The reasons for the Haval H2 generator not generating power and lacking power assistance: Check if the battery is faulty, or if there is poor contact, short circuit, or open circuit in the wiring, which prevents the generator from working and supplying power, resulting in the phenomenon of no power assistance. The battery is an essential component of a car, divided into traditional lead-acid batteries and maintenance-free batteries. The Haval H2 is a compact SUV launched by the Haval brand under Great Wall Motors, with body dimensions of 4335mm in length, 1814mm in width, and 1695mm in height, and a wheelbase of 2560mm. The Haval H2 adopts a new power combination of a 1.5T high-efficiency and energy-saving engine independently developed by Great Wall and a Getrag wet 7DCT transmission, with automatic transmission models standardly equipped with engine intelligent start-stop.
My old Haval H2 also had the issue of the alternator not generating electricity, leading to no power steering—the steering wheel was as heavy as pulling iron, extremely dangerous. Common reasons for the alternator not generating electricity include a loose or broken belt that can't drive the alternator components, a malfunctioning voltage regulator causing unstable output voltage, or internal parts of the alternator aging, such as worn carbon brushes or short-circuited coils. All these prevent the battery from charging, causing the Electric Power Steering (EPS) to fail directly and making control difficult. When I encountered this before, I found the fuse was blown, and replacing it for a few dozen yuan fixed the issue. But if the alternator is completely broken, a new part needs to be installed. It's even worse on long trips—suddenly losing power steering on a curve poses a high risk of losing control. It's recommended to check the fuse box and belt condition first after parking, and go to a professional repair shop promptly—don't delay. Don’t skimp on regular maintenance; testing the charging system every six months can prevent issues.
Driving the Haval H2 when the alternator fails and power assist disappears is really unlucky. The steering wheel becomes as heavy as dragging an iron block, making driving nerve-wracking. The cause is mostly an electrical issue, such as rusted wire connections causing poor contact, or the alternator belt being loose and slipping, stopping the charging function. If the battery isn't charging, the power assist system will fail. I once encountered this when a fuse blew, and I fixed it myself by replacing it—simple and cost-effective. But worse scenarios could be a burnt-out alternator or a faulty voltage regulator, which would be more expensive to replace. Don't ignore driving safety; losing power assist on the highway can easily lead to accidents. Now I know to carry a multimeter to check the battery voltage—if it's below 12V, it indicates an alternator problem. After repairs, test-drive more to ensure everything is normal before feeling at ease.
Generator not generating power and losing power assist is a serious issue. Common causes include generator damage, short circuits, or blown fuses. This can lead to battery depletion, power steering failure, and dangerous inability to turn the steering wheel. Immediately stop the vehicle to check fuses or belts. If unresolved, call for a tow truck. Safety first, maintain regularly.
