Battery light stays on in your Chevy silverado 2005?

test the voltage on the battery first, then on the alternator. If its good then it could just be the diode in the alternator. I would suggest you replace it becuase eventually your alternator will die and the battery will not get charged leaving you stranded somewhere. It is possible to just be a battery but you wont know unless you have the battery tested. check the voltage on the battery and the alternator before you do anything else.

Why won't a 1994 Chevy cavalier start unless it is jumped. The ABS makes a clicking noise and we have changed the alternator.?

Generally, if a car engine will not turn over without a jump start, the battery is not charged. Either the alternator is not charging it, or the battery has failed and will not hold a charge. Since you have replaced the alternator, that leaves the battery. You can have your battery tested at an auto parts store before buying a new one. It is also possible that there is something draining your battery while the engine is off. The clicking noise from the ABS indicates possible electrical system malfunctions that are best diagnosed by a professional mechanic.
