my Volkswagen Golf won't start and just clicks what should I check

Solution

1. Preparation

• Gather tools:
  • Multimeter
  • Socket set
  • Wrench set
  • Battery terminal cleaner
• Ensure the vehicle is in park (automatic) or neutral (manual) and the parking brake is engaged.

2. Battery Maintenance

1. Disconnect the Battery:

   • Use a wrench to disconnect the negative terminal first, followed by the positive terminal.
   • Safety Warning: Always disconnect the battery before working on electrical systems.

2. Clean Battery Terminals:

   • Use a battery terminal cleaner to remove any corrosion from the battery terminals and cable ends.
   • Reconnect the battery terminals, starting with the positive terminal, then the negative terminal.

3. Battery Replacement (if necessary)

1. Remove Old Battery:

   • Open the hood and remove any brackets or clamps securing the battery.
   • Lift the battery out carefully, as it can be heavy.

2. Install New Battery:

   • Place the new battery in the tray and secure it with brackets or clamps.
   • Connect the positive terminal first, followed by the negative terminal.

4. Starter Motor Inspection

1. Access Starter Motor:

   • Depending on the model year, you may need to remove components for access (e.g., the air intake).

2. Inspect Connections:

   • Check the wiring harness and connections to the starter motor for tightness and corrosion.

3. Test Starter Motor:

   • If connections are secure, use a multimeter to test the starter motor. If it shows no continuity, replace the starter motor.
