증상
자동차가 시동이 걸리지 않음... 알터네이터인가 스타터인가?
처리 내용
스타터와 알터네이터를 구분하기 위해 배터리 전압을 확인할 수 있습니다. 엔진이 꺼져 있을 때는 약 12.6V, 엔진이 회전할 때는 13.5-14.2V가 나와야 알터네이터가 정상입니다. 스타터 불량이 의심됩니다. 시동 시도 중에 전류를 측정하면 좋은 판단 자료가 됩니다. 보통 전문 측정기로 하는데, 정비소나 자동차 부품점에서 테스트해 달라고 요청하는 것이 좋습니다. 불량 모터는 보통 매우 높은 전류 소비(또는 전혀 없음)를 나타냅니다. 그러나 자동차가 움직이지 않는다면... 스타터가 작동할 때 배터리 전압이 크게 떨어지고, 작동하지 않지만 시도하고 있다면 더 크게 떨어집니다. 볼트계가 있다면 시동 시도 전후의 전압을 읽어 볼 수 있습니다. 전압이 유의미하게 떨어지면 모터가 작동하려고 하고 있다는 뜻입니다. 그렇지 않다면 모터를 정비소에 가져가 수리/교체할 시간입니다.

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.
