The electrical system of a truck is an extremely important component for the proper functioning of all devices. The experts from the AWHelp24 truck service highlight three main problems with the electrical system in trucks and buses: damage to the power cables, defect in the starter and the alternator.
1. A modern truck consists of tens of kilometers of cable, which are combined into thick cable harnesses and branched along the car. There are so many bundles of cables in the truck that you simply cannot do without a professional electrician with diagnostic equipment.
The main reason for the malfunction of electrical devices is a connection failure of contacts and wires due to oxidation, friction, pollution and water ingress. If at least one or two contacts (wires) are damaged, this can result in serious malfunctions in many of the truck's electrical systems.
AWHelp24 service experts carry out the following cabling repairs:
- Finding and correcting wiring breaks
- Restoration of wiring after short circuits and tearing
- repair of electrical equipment
- Exchange and repair of wiring harnesses
- repair of lighting
2. The starter plays an important role in the operation of the truck. Thanks to its function, the engine can start.
Trucks can stop many times when transporting goods, the engine is then switched off and restarted frequently. This directly increases the load on the truck starter. Although its working period is only short, the mechanical load is considerable, which leads to wear of the device components.
Malfunction of the starter usually occurs at the worst moment: the engine does not start, only the click of the relay and the buzzing of the starter can be heard. The starter diagnosis is an inevitable part of a repair that every driver is confronted with.
3. The alternator is rightly considered the "second heart" of a vehicle. Its task is to generate electricity for the operation of electrical devices and electronics in the car and to charge the battery. A malfunction of the alternator means that long-term operation of the truck becomes impossible because the battery power is very limited. The alternator of a heavy truck is subjected to considerable loads, which is why a repair or a complete replacement is necessary over time. To prevent the alternator from failing on the road, it must be checked regularly and any errors rectified on time.
There are several reasons why the alternator no longer generates energy:
- brush wear;
- blowing of the voltage regulator;
- short circuit in the winding;
- blowing of the diode bridge;
- Bearings wear.
If there is a fault in the voltage regulation, the current generated can be too high (leads to malfunction of the vehicle's electrical equipment) or too low (in this case, the deficiency is compensated by the battery, which leads to its draining and premature wear).
The work of modern cars is increasingly dependent on electronics, which is quite demanding regarding the car's onboard power quality. Even minor deviations can lead to premature failure of parts and parts groups of electrical devices.
Why should AWHelp24 be entrusted with the repair and replacement of the car electrics, the starter and the alternator?
The professional specialists of the AWHelp24 truck repair workshops have extensive experience, knowledge and skills in the field of electrical equipment, cabling and the electrical and electronic systems of a truck. You can always rely on the qualified support of our specialist diagnosticians and auto electricians.
Many car services make simple diagnoses (works – does not work) and simply replace the entire unit. The cost of this unit in a truck is quite high, but the cause of the error itself can be worth a few pennies. For example, only the brushes need to be replaced instead of the entire unit, which considerably reduces the costs for an alternator repair.
Our masters carry out installation and repair work promptly and qualitatively. At the same time, the cost of our service is lower than at other service centers. Since we have no dealer margins. Our company has been providing such services for over 15 years. Therefore, all employees, from the telephone reception to the mechanic, do an excellent job with tasks of any difficulty.
We serve all truck and bus models of the following brands:
MAN;
Mercedes-Benz;
Volvo;
Iveco;
Renault;
Ford;
DAF;
and others.
We have all the necessary parts for the initial installation or for repairs after diagnostic results. Our customers don't have to spend time looking for the right parts in other stores. We carry out the work strictly according to the results of the diagnosis and the technical condition of the vehicle. Our principle is the qualitative repair of the vehicle and not the imposition of additional services.
