So, I've got a 1991 2.4D, dead 200 miles away because the alternator housing oil bolt is stripped and it vomits oil profusely. Stripped alternator is some no-name aftermarket thing, but I have two "dead" original Toyota brand ones to work with, and taking them apart I'm noticing there doesn't seem to be a rectifier or a regulator in these things. Documents are scarce, and the car being very far away I can't just go check. Are the rectifier/regulator located somewhere external to the alternator itself, or does it somehow just not have these things?
