My 86 Daytona (2.2 turbo) charging system seems to have gone kaput. I have replace the chrysler alternator, (replacement has tested good), tested the battery (good). Seems to be some question on if the voltage regulator is internal to the alternator. Autozone shows I should have an external one about 3'x3', but I can't locate it anywhere. Firewall and left inner fender were where I was recommended to look, but I even crawled under to look around. Is this thing hidden or possibly internal? If external, can anyone tell me where it would be hiding? Thanks
