난이도 & 준비물
증상
2002년식 혼다 시빅 EX입니다. 시동을 걸면 배터리 경고등이 보통 고속도로에 나갈 때까지 계속 켜져 있다가 꺼집니다. 신호등이나 정지선에서 멈추면 다시 켜집니다. 속도를 높이면 왜 경고등이 꺼지나요?
처리 내용
알터네이터가 문제일 가능성이 높습니다. 가까운 자동부품점(Advance Auto Parts, O'Reilly, Autozone 등)에 가서 무료 진단을 받으세요. 배터리도 함께 테스트할 수 있지만, 배터리가 원인일 가능성은 낮습니다. 알터네이터의 내부 레귤레이터가 고장 나거나 다이오드 중 하나 이상이 손상된 것으로 보입니다. 엔진 속도가 올라갈수록 알터네이터도 더 빠르게 회전하므로 더 많은 전류를 출력할 수 있습니다. 알터네이터는 엔진 크랭크샤프트와 직접 연결되어 있으며, 더 작은 풀리 때문에 크랭크샤프트보다 비례적으로 더 빠르게 회전합니다. 엔진 회전수가 올라가면 알터네이터 회전수도 올라갑니다. 일반적으로 배터리가 완충되었을 때 알터네이터는 약 14.1V DC를 출력합니다. 예를 들어 알터네이터가 8V DC만 출력한다면 경고등이 켜질 수 있습니다. 엔진 회전수가 올라가면서 12V DC 정도로 올라가면 경고등이 꺼집니다.

With the untimely death of my daily Ford Focus Estate Titanium X recently it was time to find a new daily. The Focus was struck by a DHL lorry who straight-lined a two lane roundabout with me on the inside lane. Minor damage sustained but with the car on 127,000 miles the repair cost outweighed the value. Insurance pay-out was £2000. I thought about arguing for a bit more but it was a fair valuation.The Focus was both brilliant and terrible all in one. Nicknamed the Silver Bullet, it did every single family duty you can imagine from family holidays 4 up + 2 dogs, to tip runs, Ikea errands and

For those who have followed my previous MX-5 thread, you may remember that I was considering purchasing a new car for some time. The arrival of my son hadn't forced my hand per-se (we have another family car), but with the MX-5 being a two-seater, it's become such a lonely car. My wife can't come with me on any trips as there's now three of us.It's time to sell, and while I'll be sad to see it go, I'm excited to start another chapter.

배터리 방전으로 견인되어 옴. 알터네이터 불량으로 판단되어 알터네이터 교체함. 로드 테스트 중 온도 게이지가 높게 올라감. 냉각팬이 작동하지 않음을 확인. 팬에 그라운드는 있으나 팬 커맨드 시 전원이 공급되지 않음.

Also had exactly this with my E46 after replacing the alternator with a refurbished Bosch unit, changed for a second refurbished alternator and seems to have stopped the random parasitic draw. Assuming again it was voltage leaking passed one of the diodes.

시동 스위치를 켰을 때 클러스터 배터리 경고등이 켜지지 않습니다. 엔진을 시동했을 때 충전기(올터네이터)가 충전되지 않는 문제에 영향을 미치나요? 올터네이터로 가는 모든 배선은 랩 스코프로 확인했을 때 정상입니다.
