Headlights went out when I put the high beams on
Good morning. I drove my 1970 Chevelle SS396 yesterday at night. Naturally, I put the headlights on. When I depressed the high beam switch, all of the headlights went out. Just the headlights. The other lights were all on. Also, after this happened, the interior lights began to flicker. I haven't put a multimeter to it yet. I am guessing that possibly the voltage regulator started to stick and it blew the fuse for the headlights? Any thoughts would be greatly appreciated.
