Hey I have a 92-95 d15 non vtec, I just replaced my alternator two weeks ago, I was driving last night and my battery light flipped on and it sounded like a piece of metal hit the ground. I checked all my work and still have both mounting bolts and pulleys still spinnin, belt still tight, my terminals are connected fine and everything still appears in tact. I was wondering if anything else effects my battery light that could have gotten jarred or a sensor that may have broke, I was able to drive it home which was about 25 miles and still not acting like its dead just surging slightly at idle. Any Ideas that would help?
