battery light

[sho4life]

what are all the causes for the battery light to come on?

Alternator going bad I assume, not making enough charge?

Check all your connections and clean the battery terminals and if you have a volt meter check the volts at idle they should be between 13-14 volts.

Loose cables on the battery, starter and/or alternator, alternator, bad Battery, theres a ton of stuff

Best bet to try to narrow it down, hook a volt meter to the battery with the car off so you can see the voltage. Then start it and look at the volts again. Should be up near 13.5v.

Please dont post again when you have no idea what you are talking about.

The only reasons that light comes on is

-loose wire (the screwed one) but its kinda rare.
-bad alt.

I do know what I'm talking about, because the issues I mentioned happened to me. It's easy to always say the alt or the battery.
Let's see, on mine I've had the bat light come on. So for it's been the alt wire harness came loose, the wire came out of the charging post on the alt causing the issue, and the wire on the starter was covered in oil preventing it from charging.
Same problem, 3 different resolutions, none of which were the battery or the alt.

i have a feeling this battery light has something to do with the ignition fuses being blown. when i went to look at this car the key lock cylinder was pulled out of the steering column. does this have anything to do with the ignition fuses blowing from anti theft or something, i know gm cars wont run if the key cylinder is damaged..

Well you stated a bad starter and a bad battery as well , which indicates you have no clue whats going on.

Look, it doesn't matter. Listen to Phoenix, he knows what he's talking about obviously more than I do, as he so clearly stated.
Good Luck

bad starters dont make your battery light come on.

Giving him the benefit of doubt...maybe he was talking about the ground wire
because it is grounded to the starter...

The battery light will come on when the voltage coming from the alternator at the IC battery light circuit is lower than battery voltage. So bad IC or corrosion between the IC/alternator/battery could also cause it.

well what about the ignition cylinder being busted out? and the fuses being blown? ill get a voltage test on it and go from there
