Emma understood that distinction even if she couldn’t yet identify the exact fault.
She was fifteen, not a professional technician with decades of experience.
She knew she had limitations.
She had never claimed otherwise.
But she also understood something that seemed painfully obvious now: all the tests conducted inside this garage were being performed under nearly identical conditions.
The same motorcycle.
The same electrical systems.
The same engine.
The same indoor environment.
And the same sudden shutdown.
If something outside those repeated tests had triggered the original problem, simply changing parts might never reveal it.
Emma approached the Harley’s side but still didn’t touch it.
She leaned slightly to study the narrow space beneath the seat.
Ace followed her gaze.
“What are you looking for?”
“Nothing specific yet.”
“You’ve been staring at that area for a while.”
“There’s a lot of wiring under there.”
“More than people think.”
A modern custom Harley could contain electronic controls that behaved very differently from the simpler machines older riders remembered.
The engine’s mechanical strength was only part of the equation.
The computer needed trustworthy information from electrical components.
Connections needed to remain stable.
And certain faults could cause the engine-management system to interrupt normal operation.
Ace knew all of that.
He also knew how frustrating those systems could become when a problem refused to leave an obvious physical trace.
Emma studied him.
“Do you work on your own bikes?”
“Whenever I can.”
“Then you know what I mean.”
“Something can look fine until you put it in the condition that makes it fail.”
Ace considered her words.
He’d encountered loose electrical connections before.
He’d seen motorcycles run smoothly in a driveway and misbehave once vibration or movement changed the position of a wire.
