Hear clicking when you try to start the car? Understand the clues that separate a weak battery, poor connection and starter motor fault.
The pattern of the clicking is useful. Rapid repeated clicking often points toward low voltage or a poor high-current connection, while one heavier click can place more attention on the starter circuit.
The starter solenoid can repeatedly engage and drop out when battery voltage collapses under load. A discharged battery, weak battery, loose terminal or poor earth can all cause this.
A single click can mean the solenoid is receiving a command but the starter is not turning. Battery voltage and cable voltage-drop still need checking before the starter itself is blamed.
Lights and dashboard electronics require far less current than the starter motor, so they can appear normal even when the battery cannot supply cranking current.
Describe exactly what is happening and AutoAid can use the details, saved vehicle and any OBD-II code to narrow the likely causes.
