I'm with Kevin. A well set up generator with good clean connections to all of the electrical accessories (and the battery!) works superbly. I've been using a totally stock electrical system in my 30 Tudor since 1975; never had a problem on the road (including cross country trips), never overcharged/undercharged a battery, and my batteries typically last about 5 years. If I'm planning a long drive at night (e.g. more than an hour) I might bump up the charge rate with the third brush, but I'm not even sure that I need to do that. Every time I've considered something like a regulator, for example, I keep returning to the "if it ain't broke, don't fix it" mantra. The bone stock Model A is one heckuva piece of engineering.
