Starter Solenoid
The solenoid is an electromechanical relay that uses a low-current signal to close a high-current bridge between the battery and the starter motor. The 'click' confirms the internal plunger is moving, but carbon buildup or pitting on the internal copper contacts prevents the 100+ amps required for the starter to rotate from passing through the circuit. Replacing the solenoid restores the low-resistance path necessary for the starter motor to overcome engine compression.

Lead-Acid Battery (Group U1)
A battery experiencing sulfation or internal plate degradation may maintain enough surface charge to actuate the solenoid coil (low draw) but will suffer a total voltage collapse when the starter motor attempts to draw high amperage. This voltage drop causes the solenoid to either click once and fail or 'chatter' as the circuit oscillates between having enough power to close the relay and losing it immediately upon load.

Negative Battery Cable
The return path for the electrical circuit relies on a clean connection to the mower's steel frame. Thermal cycling and vibration often lead to oxidation at the frame-ground interface, creating high ohmic resistance that allows small currents (clicks) but chokes out the high-current flow required for cranking. A new cable or cleaning the mounting point ensures the circuit loop is completed without energy loss.
