I have a 67 GTX with a points style voltage regulator that has started sticking intermittently when the battery has reached full charge and there is no load on the system. If you turn on the headlights and load the system it works fine. I have used paper to clean the points and that helps for awhile.

Does anyone have a suggestion on how to better clean the points?

I really do not want to put an electronic voltage regulator on the car as they do not really look correct, but I have a date coded one I can use if I have to.

Thanks for your help in advance.
