Hi, new here. I have a 66 coupe v8 4bbl auto. I have an electrical problem that's driving me crazy. Thus far i have replaced a starter, selenoid, battery, voltage regulator, and alternator. All in that order. I have a short somewhere that is draining my battery every two days while parked. It kills the battery to the point where when i try to cranck, i get nothing. It seems to me that something is open or shorted somewhere. If the alternator was bad, could it have damaged the voltage regulator??? would that create a short that would drain a battery??? I have been told to run a continuity test using an ohm meter. If there is continuity then there is something on or open somewhere. How do i pin-point where that short is if there is one????
Thank you for your input

silly questions! Is your pos lead from the battery to the sol and then to the starter new? Do you have a volt meter? Do you have a test light?

The wife and I had a 65 Vert for about 5 years and we had a similar issue with in. It ended up being the voltage regulator. I know you have replaced yours. Also check all of the ground straps and grounding points!!

got it, yes, the voltage regulator was shorted. I ran a continuity test through the + and - cables. I had the buzzz, i unpluged the volt reg, the buzzz whent away. I replaced the volt reg and had no buzzz, unpluged and the same. I should have replaced the volr reg after the alternator. I think the originally my alternator was bad and it ended up damaging my volt reg.. I've got 12.3 v before starting, 13.6 while running and 12.5 right after running. I have measured the voltage 2 hours later, and the batt has not lost any juice. Thanks guys!

glad you got it fixed, those older systems can be a real pain to troubleshoot sometimes!!!!
