Starter Solenoid
The audible click indicates the solenoid coil is successfully creating a magnetic field to move the internal plunger. However, the internal copper contact plate has likely developed pitting or an oxide layer, preventing the 12V high-current bridge from completing the circuit to the starter motor. Replacing this component restores the low-resistance path required for the motor to engage.

12V Lead-Acid Battery (300 CCA)
The battery may have sufficient surface charge to energize the solenoid coil but lacks the Cold Cranking Amps (CCA) to sustain the inductive load of the starter motor. Under load, the internal voltage drops precipitously, causing the solenoid to engage but the motor to remain stationary due to insufficient torque.

Starter Motor Assembly
If the solenoid is delivering power, the starter motor's internal brushes may be worn or the bendix gear may be bound against the flywheel ring gear. This creates a locked-rotor condition where the motor cannot rotate despite receiving full current, often resulting in a single heavy click from the solenoid.
