Benzmac - Please correct me if I'm wrong. I have always been under the assumption that the alternator must be able to carry the full electrical load of the car, plus at least a 25 percent surplus to keep the battery charged (ie. with 100 amp. load, you need at least a 125 amp. alternator ). This is supposed to count only the equipment that would be on full time at night, in the winter,not any intermittent loads.
Is this info still correct or has the "rule of thumb" been changed?
