I have a 2003 Honda Civic Ex coupe the lights started flickering and the gauges stopped working while i was driving then they flickered again and my gauges completely shut off then the car completely shuts down. i had the battery and alternator tested both are good but i cant even get the headlights or anything to work, any ideas why its not working will be a great help

 

try jump starting the car and if that works check the tension on the alternator belt

 

If the car doesn't want to run, you either have a short, a possible issue with the ECU, or maybe even a blown fuse.

 

With it flickering then dieing I'm thinking a bad ground.
