I am hesitant to take my 2003 chevy Silverado 1500, because I have had past problems with the warning system as well as my instrument gauges. It began close to 6 days ago and the battery does appear to losing charge over the past few days but still cranked today. When I give her gas - battery gauge doesn't reflect a surge. Was planning to at least wait until the battery actually died and the truck not crank before taking action. I had the alternator rebuilt less than a year ago and I splurged on a heavy duty battery around 2 yrs ago.
Take it to Auto Zone or O`riellys and they will test it for you at no charge.They can check your charging and starting system also.Hope this helps.Good luck.
Do you have a volt meter digital there cheap about 8 bucks, check power at the battery, good battery should be about 13 volts, if its less than 12 like 11 or 10 you have a bad cell in the battery, then start it up, check it now you should have 13.5 or better, this shows the alternator is working, another way, start the truck, take the battery cable off, if the truck dies it could be your alternator just because there new doesnt male them godd, Matt,

Thanks. I guess sometimes "The battery isn't Charging" actually means the battery isn't Charging" haha. I thought it was another typical info message system malfunction on my chevy silverado 1500, since I had just recently rebuilt the alternator. I took it to my guy and he replaced the alternator system as well as cleaned the throttle body unfortunately since he did both. Im not sure which one took care of the problems I was having when my truck would stall on sharp turns, or when I slowed down significantly to make turns. Thats definitely valuable info and good to know about autozone, and O'reilly's.
