So what are the reasons for “only change without repair

After repairing and maintaining the car, many car owners have such a feeling that the replaced parts (such as car generators) cannot be repaired, but can only be replaced by new ones, and the repairman has since become a replacement.
In fact, otherwise, in the view of Master Wang with more than 20 years of automotive maintenance experience, this is a normal phenomenon in the industry. “Take the 01-07 Mondeo generator (2.0 automatic transmission). This generator does not need to be watched. I all know that the carbon brush is excessively worn, because if the idle speed does not generate electricity, if the throttle is hit, the generator will generate electricity Slowly rising. As long as the new carbon brush is replaced, it can be repaired, and at least tens of thousands of kilometers can be run. If the rotor slip ring is damaged, then it ’s okay, and you have to replace the assembly. If you repair it, you will directly spend more than 1,000 yuan for a new generator. “

So what are the reasons for “only change without repair”:
1. Not profitable and time-consuming: Repairing a generator is time-consuming and laborious. Different generators are equipped with different carbon brushes. Early carbon brushes also need to take old parts to a professional electrical wholesale store to check the purchase, and also need to master the use of soldering irons. Skills such as welding technology and the use of multimeters are too high for car owners who charge 200 yuan for maintenance.
2. Changing a new one, saving time and effort, the repairman earns much more than the maintenance, and will not attract the suspicion of the owner.
3. The early professional auto electricians who repaired auto generators, starters and other auto electrical appliances basically withdrew from the stage of history due to the single skills, narrow employment, market and other reasons.
4. Nowadays commonly known as car maintenance workers, they are mainly based on mechanical repair, knowing the fur of the circuit, let him know how to repair the generator, or change the generator, basically there is no spare time to entertain you.
5. Of course, there are still senior car electricians in the 4S shop. They are famous for their superb technology, but most of them can only solve the circuit problems that cannot be solved, or detect the early failure of the generator damage, and will not repair a generator. The bigger things are laborious and do not meet the 4S shop’s “replacement repair” service philosophy
