Hi. I have a 02 civic. I just had the head gasket, timing belt, water pump, radiator, and power steering belt replaced. It is at about 115k miles. Yesterday, while driving my car I noticed that the battery indicator on my dashboard was faintly flashing very fast. If I went really fast around 75/80mph it stopped. Any idea what this could be?

problem with the charging system. either your alternator belt is loose, your battery terminal connections are loose, or your alternator is dying.

I had the same problem minus the 75-80mph bit. My alt was bad. I had to replace it twice.

a bad alt. can also cause srs light to come on and not set any dtc's (alt will put out ~16v, and srs control unit goes into fail safe mode) ....but yeah - probably bad alternator!

Sounds like my symptoms. Had my SRS and ABS light come on and off. They would go away with the rear defroster, fog lights and/or fan blowing full blast.

Finally the battery light would come on and eventually after getting a jump from AAA, all the gauges turned off, the radio shut down and my headlights turned off. Towed it home and now it sits. Gonna test the alternator, thankfully a lifetime warranty one, battery has a warranty too. Must've been a bad alt, cuz I just replaced it January of 08.
