Top Electrician, I Repair Circuits And Look Stupid On The Whole Internet!

After listening to Cheng Lin's answer.

Lin Mu couldn't help but hold his chin.

I walked around the cafe with great interest.

Look at every light.

"Do you know when this problem started?"

Lin Mu asked.

"this......"

Cheng Lin smiled bitterly.

"I don't know the specific time..."

“But it wasn’t on Sunday in the first place.”

"Then it became stable and started happening every Sunday."

Cheng Lin felt very helpless.

This is a coffee shop.

The decoration is very warm...

Therefore, the lights are also made of warm yellow.

However......

It's this warm yellow light.

The flashing lights are far scarier than normal lights.

At night......

It's really a bit like the situation in a ghost movie.

"Master Lin."

"Look at this situation..."

"What's going on?"

Although I have no hope for Lin Mu.

But Cheng Lin couldn't help but ask.

"There is no way to draw a conclusion now."

"In your case..."

"It's really a bit weird."

Lin Mu shook his head and continued.

"at the moment......"

"We can only try the elimination method first."

Lin Mu thought clearly.

Since the final problem is reflected in the lights.

The simplest way...

Just start with the lights.

Soon...

Lin Mu found the ladder from the warehouse.

Climbed to the bottom of the ceiling.

"The lights kept flashing."

"It can only be a voltage issue."

"Is there something wrong with the transformer?"

Lin Mu had some doubts in her heart.

If it's such a simple question...

It's impossible that the first few electricians couldn't find it.

But just in case.

After a lot of work...

Lin Mu still checked the transformers of each lamp one by one.

The result was just as Lin Mu imagined...

There is no problem.

"Now we can rule out the problem of the lights."

Lin Mu came down from the ladder.

He shook his head helplessly.

at the moment......

He could only eliminate them one by one in this way.

Immediately afterwards...

Lin Mu came to the small warehouse behind the bar.

"Is there something wrong with the main transformer of these lights?"

There is no problem with the transformer of each light.

Lin Mu followed the circuit and continued to investigate the main transformer.

only......

After checking again.

Lin Mu found out...

There is still no problem with the main transformer of this light circuit.

"Master Lin."

"Is there nothing wrong with my lamp?"

Cheng Lin, who had been watching, couldn't help but ask.

"Yes."

Lin Mu nodded.

"Now we can 100% rule out that there is no problem with the lights."

"Besides, even if there is something wrong with the lights..."

"It's impossible for them all to have the same problem."

Lin Mu was a little helpless.

Although the problem with the light is 100% ruled out now.

But just for this reason...

lead to......

I have absolutely no idea how to investigate next.

"well......"

"Master Lin."

"Do you think this is really haunted?"

Hear Lin Mu’s answer.

Cheng Lin couldn't help but have a worried look on her face.

"impossible."

Lin Mu immediately answered decisively.

If there is any other problem...

This led to such a strange thing happening.

Lin Mu may also feel...

It's haunted.

but......

This may be caused by a circuit-related problem.

Lin Mu would never believe it was haunted.

Not because of anything else...

It’s because of Lin Mu’s confidence in her profession.

"That......"

"Then what's going on?"

Cheng Lin frowned, with a lingering sadness between her brows.

"mainly......"

"Today is Wednesday."

"If there is a situation on site, it will happen."

"That would be a little better."

"But now we can only rule it out."

Lin Mu said with a helpless shrug.

The flickering situation does not appear now.

All he could do was check to see if something was wrong.

"I really can't wait any longer."

Cheng Lin said with a wry smile.

"As long as the store is open, it is losing money."

"I really can't wait until Sunday..."

Lin Mu heard about it.

Just nodded.

He could understand Cheng Lin's psychology at this time.

then......

Lin Mu then patrolled the store again.

attempt......

Find some unusual places.

"The flickering light must be caused by a voltage problem."

"But there's nothing wrong with the transformers..."

"Is it possible..."

"Is it an electrical problem?"

"It's impossible, right?"

"If there is a problem with the electricity, is there anything that can cause the lights to start flickering at a specific time?"

Lin Mu frowned and thought.

But we still came to the electric switch.

I took out the voltage pen and measured it.

I found it was still very normal...

There is no deliberate phenomenon.

"Um?"

But the next second...

Lin Mu suddenly frowned.

Look at the switch in front of you.

"Boss Cheng."

"Did you change this switch yourself?"

At this time, there was a row of electric switches in front of Lin Mu.

Incredibly new...

It's like it was just replaced.
