So I changed my alternator because my volts were dropping around 11. I started the car up and drove around and it was doing the same thing. so i changed the battery and still the same thing. I kept the new battery because its a better battery anyway and I had everything tested and everything is at 14.2 volts but my gauge still says 11 sometimes and my lights dim when I put a load on the alternator/battery. anyonelse ever had this problem?
