    If you have a chain drive, it could be that. If you have a belt drive, then that discounts the chain obviously, so it could be the alternator belt's tensioner that's faulty. Alternatively it could be the pulley on the alternator rather than the alternator itself. A faulty alternator will fail to charge the battery correctly and also cause several weird electrical problems, e.g. the power steering intermittently failing.
