12V 30Ah Sealed Lead Acid Battery
The most common failure mode is chemical sulfation within the battery cells, which increases internal resistance. While the battery may show 12V at rest, it lacks the necessary Cold Cranking Amps (CCA) to overcome the engine's static friction and compression, leading to a solenoid 'click' as the voltage collapses under load.

Starter Solenoid Relay
Every start cycle involves high-voltage arcing across the solenoid's internal copper contacts. Over time, this results in carbon build-up and pitting, which prevents a low-resistance connection even when the electromagnet successfully moves the plunger (the clicking sound), stalling the current flow to the starter motor.

Starter Motor Assembly
If the battery and solenoid are functional, the mechanical failure likely resides in the starter motor's carbon brushes or the commutator. When brushes wear down to their minimum service length, they fail to maintain a consistent electrical path to the armature, resulting in an 'open circuit' condition that prevents rotation despite being energized.
