I have an 02 civic with 73k. Bought the car with a dead battery. The dealership "replaced" it before I picked it up. Shortly after the car wouldn't start, so the alternator, flywheel and starter were replaced two years ago. Just replaced the battery a month ago and the light still flickers on and off while driving. Checked the alternator belt and it looks good. Went to several auto parts stores and they did a charging system check, everything came up good. Any ideas?

Did you check that the terminals are fully tightened down on the battery posts?

Your car hasn't died at all from a lack of electrical power, has it?

nope. first time the light came on was about a year ago in a thunderstorm, heavy rain (didn't drive through a huge puddle), lightning struck nearby and the light came on for about 5 seconds, flickered then went back off. that's the closest its come to dying

and no check engine lights?

after they replaced the flywheel and starter the check engine light was on, the tech left a wire unplugged (not sure which one). since then haven't had the CEL come on once

Probably due to a cheap aftermarket alternator. Even though it checks out OK, the light will flash. That's why I suggest always using OEM alternator because you won't get that issue.

Was the alternator replaced by the dealership or by a mechanic shop?
