diagnose faulty voltage regulator causing battery overcharging?
처리 내용
The output of an alternator is typically between 13.8-14.2vdc. If you were in the 15vdc or higher range, I'd consider that the alternator is overcharging. It runs continuously at the ~14vdc range to continue to provide all the power the car needs as well as keep the battery charged. It sounds like to me your new-ish battery may have gone bad. A cell in it could have gone bad, which won't allow it to recharge correctly. This should be under warranty (though I'm assuming warranties in AU work the same as they do here in the US), so should be able to get it replaced, or at the very least load tested to see if this is the case. I am also going to assume most of the major vehicle parts stores in AU are also going to be able to test your alternator for free. I'd also check to ensure all of your connections are good. These connections are things like to ensure there is no corrosion at the battery terminals, ensure the connections are tight, ensure your ground (earth) at the body is in good sh

I drive a 97 Honda Accord and just recently started experiencing an issue where while driving, my ignition suddenly shuts off. Sometimes when this happens I’m able to turn the key and get the ignition started right back up while coasting, but usually forces me to coast to the side of the road instead to throw it in park and restart ignition (instantly, no sputtering). This problem seems to occur most frequently while driving at low speeds or stopped at a light or sign. Despite the ignition cutting, my headlights and radio, etc remain on leading me to believe that the battery is fine. I’ve take

We have a Honda Civic Hybrid with 204,000 miles on it. It’s my wife’s car and she commutes fifty miles every day in it. Late last week her IMA (hybrid battery) light came on. The last time this happened was 7 years ago. The battery pack was under warranty at the time and Honda replaced it. That warranty has since expired. We are going to take it into a Honda dealer to have the problem evaluated, but we’re trying to do our homework in advance. My wife is worried that she’s going to be told that the battery needs to be replaced. There has been no decline in vehicle performance - yet. She tells m

In a recent column a reader asked about a plug-in hybrid and the status of the gas. The discussion also mentioned the possibility that the 12v “starter” battery could drain over time. I don’t know about other cars but the Kia Niro has an “override” that can use the EV battery to start the car. That was the situation when we originally bought our Niro. There is a button on the dash that, if the 12v battery will not start the car, enables the starter to pull the necessary power to start the car. The battery then charges as normal. We have had no starting problems since that initial situation whe

2012 Malibu, 140k. Started about 1-2 months ago. It cranks but doesn’t start. The lights, radio, etc, come on just fine. I replaced the battery first off. The parts shop said the battery was borderline, it was due, so I replaced it. Still having it. Sometimes it starts and runs fine. Sometimes it cranks but doesn’t start. Sometimes it starts for a second but then dies. Sometimes it starts and rumbles and shakes like crazy, and then dies. I’ve had the fuel pump relay changed twice. My shop is saying the fuel pump is testing ok. Earlier tonight, when it was cranking but not starting, I took out
