Adjusting an "external" regulator [Delco] can be done if you can remove the cover. You have to have an analog voltmeter to read volts---not a digital. With the cover off, find the "contact" that controls the field. The coil will control a movable contact plate that can touch either of 2 stationary points on the frame of the coil. With the engine running, use a finger to move the contact up & down while watching the voltmeter. The "up" position delivers maximum output--the"float" position --in between --& not touching either point will give ordinary load charging. When touching the "bottom" contact it will give 1 amp of charge. Set the movable contact-- by adjusting the spring tension-- for 13 to 13.4 volts on a fully charged battery. This is the "float" position.
