Take your battery to get tested first. Usually any auto parts store will do it. If the battery is good then check the alternator. To do this you have to physically take the alternator out and take it to the store unless you have a tester than you can test the alternator while its in the car. hope I was of some help.

You might not have a good connection on your jump. Remove the battery and alternator and have both tested at your local parts store. My guess is the alternator is bad and the battery just needs a charge. If they both test good, you have a short somewhere in the truck.

2006 Chevy Malibu will not start. The car was running fine. We pulled into the garage, turned off the car in order to empty groceries. We went back out and tried to start the car, but all the lights...

Try jumping. Suspect battery or alternator. If you can jump it, use voltmeter to check battery voltage with engine running. If voltage is less than 14, your alternator is bad. If you don't have a meter, take the alternator to be tested.

2006 Chevy Silverado alternator intermittent charging

Perfectly normal.
Starting with the 2005 model year, light duty full size pickups and utilities are equipped with a new Regulated Voltage Control (RVC) system. This system reduces the targeted output of the generator to 12.6-13.1 volts when in "Fuel Economy Mode" to improve fuel economy. The generator may exit "Fuel Economy Mode" if additional voltage is required. This will cause the voltmeter to fluctuate between 12 and 14 volts as opposed to non-regulated systems that usually maintain a more consistent reading of 14 volts. This fluctuation with the RVC system is normal system operation and NO repairs should be attempted.
