Pulsating lights

Well Dan I did everything you said, and still no go. I ran the wires like you said from the ground off the alternator to the mounting screw on the regulator, from the regulator to the neg side of battery terminal, and I still have hollywood lights. I changed the volatage regulator, and that didn't work either. I pulled the bulk head plugs out and replugged them in, taking and small screw driver and pushing on each of the terminals to make sure they are plugging in tightly..still no good. Any more ideas you can send my way will be appreciated. Do they make a terminal cleaner that i can spray into the bulk head terminals that will clean them? Oh I also cleaned the grounds on the front and back light harness where they ground to the body. Brian
