The test vehicle in question is a 1987 Buick Grand National. The car has aftermarket dual 11" Spal radiator fans drawing approximately 38amps. It's obvious the stock alternator can not produce enough power to keep the voltage in the 14v range. We installed a PowerBastards.com 240AMP Buick Grand National Turbo High Ouput Alternator to cure the problem. Watch the video.
