On most vehicles today the voltage regulator is built into the alternator. If that is the case then just replace the alternator. If the voltage regulator is external on your vehicle then replace the voltage regulator.

Most likely the problem is your alternator....the battery light actually does not monitor battery condition, only the charging system. I'd check the voltage regulator and the fuses first. The fuses are the cheapest fix and the voltage regulator will run about 25% less than an alternator.

Most likely, your starter isn't the problem. You may have a bad alternator. Usually when your battery doesn't recharge properly it's an issue with the alternator. Have a mechanic inspect the alternator if you're not comfortable doing it yourself. If it is an issue with the alternator, it's a pretty cheap fix.

How can I test my alternator to see if it is discharging my battery?
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
