May be weak and only charging enough to keep the truck running with nothing left to charge the battery. Out of ideas

Why might the battery light flash on 2002 Chevrolet Tahoe?

If the battery light is displayed when the engine is running, you may have a problem with your charging system. The battery display will stay on while the key is in RUN until the engine is started. If the message stays on after the engine is started, it could indicate a problem with the generator drive belt, or some other charging system problem. Driving with this message could drain your battery. If you have to drive a short distance, turn off all accessories such as heater, air, radio, etc. and get it checked right away.
