I have a bit of a problem. I have a 97 S-10 Blazer LS with 4.3. Today on the way to work the little battery sym poped up. The gauge read just under 12 V. To me this sounds like a alt. or battery problem. Does anyone have a opinion. I was able to restart it and drive it home with no light and the gauge dropped a bit more.
Local store sell 2 compatable alts. One is $30 (? amps) and the other is $157 (100 amps). Both are refurbs. Is the regualator built in the alt?
Plz help!

Yes, it sounds like the alternator. If you truck has air and power windows ect it probably needs the bigger one. I haven't seen a $30 alternator in a very long time. On a truck that new I would be surprised if it has 2 different options. Call another parts house to be sure. Do yourself a favor and get the battery and the alt tested to be sure. A bad battery can kill a good alternator. GL
