Question about 1999 Pontiac Grand Am GT
This started a few weeks ago..I was driving and the battery light came on, went to auto zone, said the alternator was bad. So I got a new alternator and battery. Few hours later, the light came back on. It will stay on at very lo rpm's (usually below 2k) but as soon as you give it a little gas, it goes out, let off, then it comes back on. I even plugged in a new main computer under the hood, but it still did the same evact thing, any ideas where the problem might be coming from?
Check the bettery cables at the bettery and at the engine and stater, if they are corroded rusty or greasy, it will cause this problem. If there is corrosion at the battery replace the terminals with after stock from autozone. Also check the wires at the alternator to make sure they are also ok.
