This is a video of a newly replaced alternator on a Toyota Yaris 2007 MY with a 1.5L four speed auto set up. The car was making a whirring sound, and would increase in volume when accelerating. Also, it would idle rough due to the lack of electricity that it was being provided. This is the video after I installed a new (remanufactured alternator).
