The girl did not look at him.
She took the flashlight.
Bent beside the motorcycle.
Followed the main harness from beneath the seat.
The biker watched.
She touched nothing initially.
Just looked.
Her flashlight moved slowly across wiring.
One junction.
Another.
A connector tucked where a section of harness passed near the rear fender support.
She asked:
“Can you start it with the seat up?”
“Yes.”
“Do it.”
The biker did.
The engine started.
The girl waited.
Four seconds.
Dead.
She moved the harness slightly.
“Again.”
Start.
Four seconds.
Dead.
She looked at the connector.
Then at the spray bottle.
The mechanic who had laughed shook his head.
“No.”
The girl asked:
“Why?”
“You’re about to spray water on an electrical system.”
“Yes.”
“That is exactly what we avoid.”
“I know.”
“You don’t spray water on customers’ bikes.”
She looked toward the biker.
“Your bike?”
He nodded.
She held up the bottle.
“I want to mist one connector.”
The biker looked toward the garage owner.
The owner shrugged.
“At this point we’ve replaced half the machine.”
The biker looked back at the girl.
“Do it.”
She started the bike first.
The engine idled.
She sprayed one very light mist across the connector housing.
The engine died instantly.
Not four seconds.
Immediately.
Nobody moved.
The girl looked at the mechanics.
“Again.”
The garage owner leaned closer.
She dried the connector with compressed air.
Started the bike.
It ran.
She misted it again.
Dead.
The garage became silent.
The girl placed the bottle down.
She separated the connector carefully.
Used the flashlight.
Then a small inspection mirror.
“There.”
The oldest mechanic stepped forward.
“Where?”
She pointed toward the weather seal.
At first it looked fine.
Then she flexed it slightly.
A hairline crack opened.
Tiny.
Almost invisible.
The seal had split around one corner.
Inside, one terminal showed the faintest trace of green corrosion.
The girl said:
“Water gets inside.”
The seventeenth mechanic leaned closer.
“That little?”
“Yes.”
“Why no permanent fault?”
“Because when it dries, contact comes back.”
The garage owner nodded slowly.
“And when moisture bridges or changes resistance—”
“The computer sees nonsense long enough to shut the engine down.”
The girl looked toward him.
“Then it dries.”
“Then everybody tests it.”
“And it looks fine.”
The biker stared at the connector.
“How did seventeen mechanics miss that?”
The girl wiped her fingers on a shop towel.
“They were looking for something broken all the time.”
She pointed.
“This only breaks when it gets wet.”
