My battery went dead in my 1992 Honda Civic. I jump started it and it started and ran good for about 5 minutes. I drove it to the store, and the accessories stopped working on the way there, the speedometer stopped working, the lights didn't work, etc. When I got to the store, I sat in the parking lot to see if it would keep running. After about five minutes, the car died. I went in and got the new battery and replaced it. The car started back up fine and I drove it home, but the battery warning light on the dash was on. Now, when I turn the headlights on, other accessories dim or stop working. Also, I checked the battery, and the voltage doesn't go up as it should after you start the car. I'm pretty sure I fried something when I drove on the bad battery. Did I ruin the whole alternator, or is it maybe the voltage regulator, or something else? Thanks
Also, my battery died because I let the car sit for three months.
