Thanks Robert

 

welcome to the forum! just as a side note for future referance throwing parts at a car and randomly replacing things is most peoples first instinct but it's going to cost a LOT more than just asking a few questions....


First off make sure the fluid level (water) in the battery is full, if not add some distilled water (not tap water or your battery is shot...) if it's a sealed battery then put a tester on it and see what it's putting out for power, if it's at 12-14volts that's great, then try to start the car with a tester on the battery, if it drops to almost no voltage then that means the battery can't handle a load, if you've checked/tried the first things I mentioned and it doesn't resolve the issue then replace it, your alternator is probably fine, probably was fine to begin with... I bet that battery is a POS but test it and check things first just to be safe.... if you still have concerns over the alternator then put a tester on the battery cables with the car running, at idle it should read 13-16 volts....

 

The light is probably on because the charging system isn't working/properly. Have you checked the fuses?
