Today I was driving my CRX and the battery light came on (and has stayed on since). A stench of something burning (cant identify exactly) came through the vents at almost the same exact time. I checked and cleaned the connections, I checked the battery. A friend of mine used a voltmeter, and its fine at 12.5 or so. But it seems to not be taking a charge from the alternator because it goes down to 12 after I turn the car on. If something is burning, i cant find it. Any ideas what it might be?
