I have a 1986 honda prelude with the 1.8L engine in it. When you increase the rpm's above idle or turn on a perifial device such as the head lights the voltage drops to 11.5v. At no point will the voltage go above 12.5v I have put in a new alternator, a new belt, a new external voltage regulator. I also have new battery cables, a new battery and a new starter. What else can I check?
