Why does my truck say charging system failure?
What's happening when the battery/check charging system light comes on? Whenever this light goes on, it means that the vehicle is running solely on battery power. If the problem continues and your charging system fails, the battery won't be able to recharge and it will soon run down, leaving you with a dead battery. via
What could cause charging system failure?
Another common problem that can cause the charging system to fail is a broken alternator belt or one that is worn so bad it slips badly. If the alternator works properly but the belt doesn't spin it fast enough, the voltage output can drop and cause the system to act as though the alternator doesn't work. via

Can a bad ground cause alternator failure?
Poor ground connections are an often-overlooked cause of low charging output and alternator failure. Check for voltage drops at the positive and negative battery cable connections, the alternator BAT+ power connection and the engine ground strap(s). Voltage drops on the negative side can cause overcharging. via
