It maybe be a loose wire that is preventing the alternator from charging.

When you have the key in the II (accessory) position but the engine off, is the alt light on (along with other lights)? It should be. If not, look for a loose wire at the alt. The thin red has a spade connection and the thicker blue grounds the alt to its mounting bracket.

If the alt light is on in the II position and engine off, does it go off when the engine is started? If not, your brushes are probably bad.

If the alt light goes off when engine is started, suspect a bad battery. If you have a multimeter, check voltages at the battery: engine off (about 12V), engine on (about 14V). If these voltages are okay then your battery is probably not holding a charge.
