Battery Idiot LightIf by battery light you mean the instrument panel charging system warning light, then that means that more electricity is flowing out of the battery than is being put into it.The charging system is not putting out as much electricity as the electrical system is using.

Something is causing a drain on the battery even with the vehicle off and nothing turned on. A good mechanic can do a drain test on the battery to see what may be draining the charge. A dead cell in the battery itself will also cause the battery to go dead. Disconnect the negative battery cable overnight and if the battery is dead the next morning it has a dead cell and must be replaced. If not look for a light that is on or a relay that is stuck.
Very likely an alternator problem; if the alt is not working soon the battery would be drained and the truck would shut off.
