HOWO Cargo trucks sold by HOWO Special Truck Ltd. have advanced electrical systems. These systems include batteries, generators, lighting and sensors. These components help the truck to function properly in different transport jobs. As trucks are becoming more and more dependent on electronics, it is important to keep the electrical system in good condition. So find out what are the common faults in the electrical system of HOWO cargo trucks? can help you use your vehicle better.

Battery-related faults
The battery is the main part of the electrical system of a HOWO truck. It provides power to start the truck and run other electrical components. When the battery is low or old, you may have difficulty starting the truck or notice a lack of power. Older batteries, especially in cold weather or under heavy loads, may have trouble holding a charge and may not function properly.
Loose or corroded battery connections are also common. These problems can prevent power from flowing properly, causing the truck’s electrical system to work poorly or not start at all. This can happen with prolonged use or exposure to harsh conditions. Regular inspection and cleaning of battery connections can help prevent these problems.
Charging issues also require attention. If the generator or voltage regulator fails, the battery will not charge properly and the truck may lose power while driving. You may see dashboard warning lights, dimmed headlights, or other electrical problems. This is why the alternator and voltage regulator need to be checked regularly. This will help keep the battery charging system working properly and prevent these problems.
Generator and charging system faults
The generator is an important part of the electrical system of the HOWO truck. It charges the battery and supplies power to the truck’s electrical equipment. If the generator isn’t working right, the battery won’t get enough power, and you could lose electrical support while driving. Signs of a problem include a battery warning light on the dashboard, dimmed headlights, or weakened electronics. If you ignore these signs, the truck could break down.
The voltage regulator controls the power coming from the generator. It ensures that the battery and electrical components receive the right amount of power. If the voltage regulator fails, the voltage may be too high or too low. High voltage can damage the battery and electronics, and low voltage can stop the battery from charging properly. It is important to check the voltage regulator frequently and replace it if necessary.
The generator belt connects the engine to the generator and helps it run. If the belt is loose, worn or broken, the generator will not work and the battery will not charge. This can lead to problems with the truck’s electrical system. Regularly check the belt for wear and tension and replace it if necessary.

Lighting and signalling system faults
Lighting and signalling systems are important for the safe use of HOWO vans. Common problems with headlights and tail lights. These mainly include damaged bulbs, loose connections or poor wiring. If these lights don’t work, they reduce visibility at night and increase the risk of accidents. Regularly checking bulbs and wiring can help prevent these problems.
Turn signal and indicator light problems are also common. They can be caused by burned out bulbs, faulty relays, or shorted wiring. If turn signals fail, drivers are unable to warn other vehicles, which reduces driving safety. It’s a good idea to check the turn signal system frequently and replace any damaged bulbs or relays immediately.
Problems with the interior lights or dashboard display can affect the driver’s ability to monitor the truck. Problems with interior lights or dashboard displays are usually caused by wiring problems or blown fuses. Checking the wiring and replacing fuses can fix these problems and keep the lights and display working properly.
Sensor and control module failure
Sensor problems are common in HOWO cargo trucks. Important sensors, like those that measure temperature, pressure, and speed, help monitor how the truck is running. When these sensors fail, they provide incorrect information that can affect the engine’s operation. For example, if a temperature sensor stops working, the engine can overheat, which can cause damage if not fixed.
Control module failures are also serious. The engine control module (ECM) and transmission control module (TCM) manage the truck’s critical systems. If these modules malfunction, the truck may not start, lose power, or be able to drive properly. When these modules stop working, the performance of the truck can be greatly affected.
HOWO trucks also use a system called the CAN bus to help the different parts of the truck communicate. If this system fails, the truck may not be able to send or receive important information. This can cause warning lights to come on or other parts of the electrical system to malfunction. Regular maintenance of these systems is important to keep your truck running smoothly.
Fuse and relay failure
Blown fuses are a common problem in the electrical system of HOWO trucks. When a circuit is overloaded or a short circuit occurs, the fuse blows to protect the truck’s electrical components. This safety feature prevents further damage. If a fuse blows, it is important to find the cause, such as a short circuit or excessive power usage, and fix it. After that, you can replace the fuse to get the system working again.
Relays control important equipment such as headlights, air conditioning and fans. If the relay is damaged, these devices may not turn on or work properly. For example, if the headlights don’t turn on or the air conditioner doesn’t cool, a damaged relay could be the cause. Regularly checking relays and replacing them when needed will help keep your truck’s electrical system running smoothly.

Electrical system fault prevention and maintenance
Regular inspection and maintenance: Regularly check the battery to make sure the connections are clean and tight. Also check the generator and voltage regulator to make sure they are working properly. This helps prevent electrical problems while driving.
Fix small problems quickly: If you notice a small problem, such as a broken bulb or loose wire, fix it as soon as possible. Taking care of small problems early can prevent them from turning into bigger problems. This will keep the electrical system running smoothly.
Use Diagnostic Tools: Use professional diagnostic tools to test your electrical system on a regular basis. These tools can find hidden problems before they get worse. This helps keep the electrical system working properly and prevents major breakdowns.
