I had an issue with my battery on my 85 302 cfi and the alternator wasn't charging the battery. So, I got a voltage regulator from autozone and it started charging correctly, but it would drain my battery. I got a new one today, hoping it would fix some of the issues im having with my lights. My rpms wont read until I have my headlights switched. Very weird. It didn't fix anything. And I have yet to see if it drains still. Is this my regulator? Or could it be a bad connector?
