07 silverado battery light
A couple of weeks ago I attempted to jump start a coworkers truck from mine. I connected the batteries directly to each other and he started his truck. His truck died and would not idle and we gave up. Two days later my battery light came on, my battery is 2 months old. I replaced the battery and 2 days later the light came on again. Did I screw up my voltage regulator in my alternator?

Might try having the alternator load tested, but do check all of your fuses to make sure its not as simple as a fuse..

Put a volt meter on the battery with the engine running and see if the reading is at 14 volts. If it is around 12 volts, the alternator is not charging.

At start up, the gauge in the truck shows about 15 volts, and if I drive a while it goes to 14. The autozone tech put a portable tester on the truck and said the alternator and starter were good. I will start looking at fuses today. Thanks for the replies.

With the truck off I have 12.45 volts at the battery. After start up, I am getting 14.25 volts. Any suggestions on which fuses or relays to check, or pull and check them all?

The battery light is really an alternator light. It comes on when the truck does not see charging voltage. Some alternators start to fail when they are warm. You need to have the alternator tested while the battery light is on as that is the only time what ever is failing is bad for now.
