Well Yesterday I went to drive my car and as soon as I fired it up the battery light came on. I'm like wtf, go to roll my windows up, they go super slow, go to turn my stereo on, turns off. I shut the car off, look at the battery (stock ac delco) the little spyglass is green which apparently means its charged. So I turn the car on, give it a couple revs, light goes off. Turn the stereo on, lights back on. Rev it high lights goes off till I drop the revs. I'm assuming this means my alternator is shot, anyone care to agree/disagree.
Or its a loos connection of either your positive or ground wire.
I checked all connections, they were good, check voltage at battery and its good, checked it at the alt and it was like 10 volts running, so I pulled the alt out (took 20min) and I'll get my new one tommorrow.
