    Purchased this about a year ago to replace 12 year old OEM AC Delco in my GM. About 8 months after I got it the rectifier started going out, 2 months later the voltage fluctuations were so bad the headlights were strobing at idle and my electronics started acting up. Ranges between 8 volts and 18.
