During the winter months, the condition of the starting and charging systems in your Chevy becomes even more important, due to the extra power demands that the cold presents, and poorly working Chevy alternator could render your vehicle unable to start in the morning. Though the unit may, in rare circumstances, fail entirely in less than a second, it more typically fails over a period of days, weeks or even months, with the power available slowly declining. Within the unit are three distinct circuits, which produce three separate electrical currents in one complete rotation. If one of these circuits fails, the total amount of current produced by the Chevy alternator will be reduced by a third. This will reduce the total amount of power left to recharge the battery, after all of the accessories and lights within the vehicle get their needed amount of electricity. In addition, more demand will be placed on the other two circuits, accelerating the eventual demise of the entire Chevy alternator.
