Jiang Meimei was in the outer room, circled Yao Yuan and the sewing machine, then put her head into the room, and shouted at Jiang Kangkang: "Sister."

Jiang Kangkang still only focused on nailing his own buttons, or ignored her. Meimei always carried her on her back and refused to call her sister, and she was also angry.

Yao Yuan knew that Meimei was running back, and most of the time it was about to find him. Ye Owl came into the house and came without any trouble. He also deliberately ignored her and focused on her extended cuffs.

Jiang Meimei finally couldn't hold it in anymore and asked Yao Yuan: "A omnipotent stupid brother, do you understand the lathe?"

Yao Yuan said while working: "I should understand the 16 you use. What should I do?"

Jiang Meimei asked again: "What about 20?"

Yao Yuan stopped the sewing machine and asked her: "What are you doing?"

Jiang Meimei said, "Tell me first if you understand?"

Yao Yuan said contemptuously: "There is nothing to understand?"

Jiang Meimei asked again: "What about electrical control?"

Yao Yuan said in a word: "What's the difficulty of just a few broken contactors?"

Jiang Meimei said: "The 20 in our group broke and the work was over. The electrician class couldn't repair it for a day. I had no work to do this process."

Yao Yuan said: "You have no work to rest. You don't care about pieces and don't deduct money if you do less."

Jiang Meimei said anxiously: "You don't know. If you delay, you will not be able to complete the task. Our class's advanced mobile red flag will not be able to be protected."

Jiang Kangkang interrupted on the kang in the inner room and said, "I fucked the deputy squad leader. You see, you are so worried. If you can't save it, you can't save it. What's so great about it?"

Jiang Meimei said: "What do you know? I'm thinking about letting the factory recommend college! If you don't keep it advanced every month, can someone recommend me?"

Jiang Kangkang asked, "Don't you want your stupid brother to repair the lathe for you, right?"

Jiang Meimei said proudly: "My stupid brother is omnipotent, maybe he can repair the machine tool!"

Jiang Kangkang said, "That's not possible. Even if he can repair it, he can't go. Otherwise, everyone would know that he is not stupid and would have to go to the cleaning team to report in the morning. I can't keep this house for making clothes." Jiang Kangkang didn't dare to say the rest.

If Zhang Shuncai next door knew that Yao Yuan was not stupid, he would have suspected the haunted thing.

Unexpectedly, Jiang Meimei talked about her sister: "Why are you so confused? The fool continues to pretend to be a fool. What should you do when you marry you in the future? If everyone knows that you have married a fool, aren't you afraid that others will laugh at you? It just happened to let everyone know that the fool is not stupid. Not only is he not stupid, he is also an amazing talent. You will be more face-saving when you get married in the future!"

Jiang Kangkang stared at Jiang Meimei and scolded: "Little girl movies, there is nothing you don't want to get involved! I just want to marry a fool, can you care?"

As soon as this sentence was said, it was equivalent to admitting that she liked Yao Yuan. After saying it, her face turned red first.

Yao Yuan stopped working and was stunned.

He didn't expect that his reputation as a fool would hurt Jiang Kangkang! Yes, everyone knows that he is a fool. A girl like Kangkang actually married a fool. How much reputation pressure will she face? Also, Aunt Jiang gave her beautiful daughter to the fool. Is Aunt Jiang's fault or is it something shameful about Kangkang?

He suddenly asked, "What's wrong with that 20?"

Jiang Meimei said: "If you change the control transformer, it will burn. Three of them have been burned this day. The electrician team can't find any problem and dare not change it."

Yao Yuan asked: "There are no electricians there, are there any multimeters used by electricians?"

He is a graduate of the mechanical and electrical major and has many years of work experience, so this problem may not necessarily stump him.

Jiang Kangkang asked, "You really plan to repair it? After you repair it, the fool knows that you are not a fool. How can you play a fool in the future?"

Yao Yuan stood up, walked to the inner room, looked at Kangkang and said, "Kangkang, I can't be too selfish. In order to be a fool, I ignore your feelings and Aunt Jiang. How can this be worthy of you?"

After a moment of confrontation, Yao Yuan was stunned. It seemed that he had thought of his reputation.

"But," she asked him in a low voice, "What if next door knew you were not a fool?"

Yao Yuan said: "When the time comes, soldiers and generals will block water and soil, and these are not as important as your reputation."

Jiang Kangkang stopped talking.

Although Jiang Meimei usually fights against Jiang Kang, she is still considering her sister after all. She has long thought about this problem, but her thoughts are all in her stomach and she doesn't say it easily.

The electrician team worked for a day but failed to repair the lathe and couldn't walk. The factory kept asking for progress, and even the workshop director was anxious. At night, the workshop director did not ask the electrician team to go home, so he looked for the reason in front of the lathe. If he couldn't repair it, he would not go home!

The factory has been loose for many years, and the skilled workers have almost been exposed. The remaining people have been much worse in theory and practice, and have developed the habit of procrastination. They can't find any problems for a while, and they will all be exhausted. When the workshop director is there, he pretends to be around the lathe. When the workshop director leaves, they all run away.

At this time, Jiang Meimei suddenly felt illuminated. If Yao Yuan came over to repair the lathe at this critical moment, wouldn’t he become famous in the factory? In that case, if he resisted and married him in the future, who would dare to say that the resisted and married a fool?

Meimei is usually less talkative, but she is very brave, and she wants to do it. She went directly to the workshop director and said that she knew an electrical expert and could repair everything. Why don’t she find him here to try it?

At this time, the workshop director was so angry that he couldn't care about these things. He finally caught a life-saving straw, but without thinking about it, he immediately asked Jiang Meimei to find her.

On the way back, Jiang Meimei was still thinking, what if Yao Yuan couldn't do it, and he couldn't do it? But since this big fool had a good brain and was as good as a helper, he had never seen anything he couldn't do.

Even if he doesn't know how to do it, at most he will tell the workshop director that she would be done if she didn't find that person?

The little girl was quite stunned, dared to think and do it, so she came back to find Yao Yuan.

The electrical structure of the lathe in the past was a very simple thing for Yao Yuan. He quickly understood Jiang Meimei's painstaking efforts. At the critical moment, Meimei still had to think about resistance and look to her sister.

When Jiang Meimei took Yao Yuan into the workmanship workshop of Xiaopin workshop, the workshop director who was looking forward to the stars and the moon was immediately stunned.

"Jiang Meimei!" He shouted at Meimei, "What are you kidding me? Isn't this Yao Dasha? He can repair lathes, and I can also fly planes!"

Several electricians standing next to the machine tool laughed with a "coaxing" sound.

Zhang Jianguo laughed so hard that he couldn't straighten his waist. He pointed at Jiang Meimei and said while laughing: "Meimei, you, have you taken the wrong medicine? Why did you get the fool? I can't beat him? If you let him repair the machine tool, you might as well give him a sledgehammer and let him smash the lathe into scrap iron. That's what he can do!"

"Get out!" Yao Yuan suddenly spoke, scolding Zhang Jianguo, "Pick me up with the multimeter!"

Everyone is stupid again now, and they are stupid and can't stutter.

Then, Yao Yuan took the multimeter, which was an old-fashioned pointer-type mechanical multimeter, which he had used in the past. Turn the gear to the low resistance gear and start measuring the output wires of the transformer in the electrical box behind the lathe.

If a failure like this is burning the transformer, it can only be a short circuit in the output, not an input problem. Otherwise, the main switch will only trip or the fuse will be opened.

Seeing Yao Yuan skillfully using the multimeter and making it very well, everyone was shocked again. They were all standing there without a single move.

Yao Yuan measured that the output circuit had a resistance value, which means there was no short circuit. This is strange. Why does the transformer burn if there was no short circuit?

He looked at the transformer model, bk-100, which can fully support the power of the control circuit. It shouldn't be? No wonder these electricians can't find any problem. There is indeed nothing wrong with it?

Yao Yuan's sweat came down.

If he cannot repair the lathe, he will definitely have to bear the reputation of a fool. If he doesn't say it, Jiang Meimei will also be affected by him.

Don't worry. He repeatedly reminded himself in his heart that the structure of this thing is very simple and not that complicated, and he can definitely repair it.

At this time, an electrician spoke: "You are so stupid, what's wrong with it? Is the sewer blocked? Why don't I find Zhang Tieshi for you, and you can use the Tieshi to clear it?"

The workshop director was also annoyed and said to Jiang Meimei: "Take Dasha home quickly and don't waste my time here!"

Jiang Meimei was quite stubborn and said with her neck in her arms, "Anyway, they can't repair it well, so why don't you let the fool brother try it? I said that if he can repair it well, he will definitely repair it well!"

The workshop director shouted at Jiang Meimei: "Jiang Meimei, you have delayed the workpiece processing time for me, you have to take full responsibility!"

Jiang Meimei muttered: "If you take full responsibility, you will take full responsibility. What's the point?"

Just as everyone was making noises, Yao Yuan found that there was a small gap under the back sled of the lathe, where the feed box was connected to the feed box. There should not be a gap in this place. He shone it with a low-pressure light with his hand, and there was a red thing in the gap.

Yao Yuan asked Jiang Meimei: "Has this lathe removed the gearbox?"

Jiang Meimei said: "Yes, the maintenance team came over to remove the gearbox and change the gears. After changing it, the control transformer burned."

Yao Yuan finally understood. When the maintenance worker disassembled the gearbox and reinstalled it, he pressed a control cable between the gearbox and the slide.

There is oil stain on the end surface of the gearbox, and the control line is crushed and the leakage is shorted after the leakage is shorted, which burns the transformer.

He didn't say anything, loosened the fixing bolts on the slide with a hex wrench to make the gap bigger, and then found a screwdriver to hook out the red wire.

Sure enough, the red wire had been flattened, and yellow copper wire was exposed inside.

He took the electrician tape, wrapped the exposed copper wire, installed it with a new transformer, sent it to the power supply, and signaled the operator to drive.

With a roar, the lathe was running normally.

This time, everyone was stunned again.

It took only fifteen minutes for Yao Dasha to enter the workshop to repair the lathe. The five members of the electrician team were busy with two shifts, but they didn't find any problem.

An electrician also saw the broken wire and figured it out. At this time, he said to himself: "No, there is electricity leakage here, why can't the multimeter measure it?"
