question for allt the 68 owners out there I have roughly an 800 millivolt drain with key off (.8V) Way too high. I finally got my service manual for this year car and have found the solution and another problem. The drain seems to be the voltage regulator. I have batt voltage going in on the orange wire. A .4V drop coming out at terminal F. An another .4V loss at the alternator. I know how to take care of the regulator to alt. problem. WHen checking thew wiring diagram, It showed that the regulator was grounded to the chassis only. Yet in the regulator testing section, it showed a ground at the regulator, and a wire going to ground on the alternator. Was just wondering if the extra wire is nonexistent or i really need it. If i Can find any extra wire laying around i will loosely run it just to see if anything changes.
