    I have a '14 LX Coupe 1.8L and added an high output alternator for car audio purposes. Long story short it ultimately stopped charging and threw a battery light. I'm told the only way to have this upgrade is to install a regulator in the alternator and bypass the vehicles factory system...

    I bought my 2012 Civic about 5 years ago, and in that time I've replaced the alternator 4 times and the battery 3. I've had various auto parts stores test the battery/alternator, and I've been replacing them at their recommendation. Until recently, I've always purchased remanufactured/lifetime...

    '14 LX sedan purchased in fall of 2017 under CPO program with 11k on it. The other day, after backing into my garage, I noticed that the headlights began to dim a bit when I turned the steering wheel in either direction. Not a major dim but sufficient to see it on the inside of my garage door...

    So, I've searched a lot and can't find anything specifically stating what the stock alternator's amperage is in the 2012 Civic Si. All the parts locations I see that mention the stock alternator either don't mention amperage at all or state N/A or TBD for the spec. I noticed the main fuse for...
