my Volkswagen Golf won’t start and the dashboard lights are flickering what’s wrong

Solution

1. Preparation

• Gather all necessary tools and parts.
• Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Battery Replacement (if necessary)

1. Remove the battery terminal clamps (negative first, then positive).
2. Unscrew and remove the battery hold-down bracket.
3. Lift the battery out of the tray carefully.
4. Place the new battery in the tray, ensuring it is properly seated.
5. Reinstall the hold-down bracket and tighten it securely.
6. Connect the positive terminal first, followed by the negative terminal.

3. Starter Motor Inspection

1. Locate the starter motor (usually found near the engine's transmission).
2. Disconnect the wiring harness from the starter.
3. Use a multimeter to check for voltage at the starter terminal when the key is turned to the start position.
4. If no voltage is present, trace the wiring back to the ignition switch and check for continuity.
5. If voltage is present but the motor does not engage, replace the starter motor.

4. Alternator Testing (if necessary)

1. Reconnect the battery and start the engine.
2. Use a multimeter to measure the voltage at the battery terminals; it should read between 13.8V and 14.4V when running.
3. If the voltage is lower, replace the alternator.
