Why don't motorcycle repair shops like to repair motorcycle circuits?

1, first of all, it's not that I don't like repairing circuits, but that I don't understand circuits, and I can't say I don't understand them (everyone has self-esteem);

2. Mechanical faults are generally visible to the naked eye, and most circuit faults need to be measured and judged;

People with high diplomas can't do motorcycle maintenance, and people with low diplomas can't know and understand the circuit.

4, the maintenance point is definitely profitable. Mechanical failure, the owner can see that the maintenance personnel are very hard, and naturally they have to collect some money; But if it is a circuit fault, it will take a long time to eliminate the fault. For example, the fault is caused by the damage of a diode, a resistor and a capacitor. It seems to the owner that these components are similar to broad beans. Is it unreasonable for you to charge 100 yuan?

There is an example in the maintenance industry, which can also be understood as a joke. The giant motor of a big factory broke down, and the maintenance personnel couldn't find the reason after several days' investigation. Finally, they found a master, but the master needed a check for ten thousand dollars. The master drew a line with chalk, saying that if you open it here, you can find the reason and repair the motor. Sure enough, it was fixed. Some people feel that they have lost money, so they ask this expert. Experts say it only takes one yuan to draw this line, but it takes 9999 yuan to know where this line is drawn.
