I have checked the battery and alternator, which came out good. I changed the alternator and it was doing the same thing. I was told that it could be the alternator connection pug in which I checked it with a test light an meter an it was good. Now I don’t know what to check next.

Hello,

This sounds like it could be a problem with your voltage regulator. I have included a list of symptoms related troubleshooting for you down below in the diagrams. Please go over it and get back to me with the pinpoint test that corresponds with it and I will get that pinpoint test back to you.

Thanks,
Alex
