Would a poorly adjusted belt on the alternator cause surges during coasting? My belt has started squealing like a biatch!!! Was wondering if this belt is too loose and is slipping big time. Stuck my head in the engine bay while it was screaming but the both belts are spinning. Not sure if it's slipping a lot or there is something else?

My thought was that if it is slipping over the alternator then the ECU may be bumping up the revs cos the alternator is not putting out enough voltage.

Anyone??
