Clicking noise coming from engine. lights blinking very fast. battery good. engine wont turn over nothing is working?

The clicking noise from the engine often indicates a weak or failing starter motor or a poor connection in the electrical system, despite the battery being good. The fast-blinking lights suggest a potential issue with the alternator or a problem with the electrical system as well. It’s advisable to check the battery terminals for corrosion, inspect the starter connections, and consider testing the alternator. If these components are functioning correctly, it may be time to consult a mechanic for further diagnosis.
