it is inside the alternator. If the voltage regulator goes bad you have to change the whole alternatorAnswerIn your 1986 Honda prelude the voltage regulator should be separate from the Alternator. It should be a small black square with a five wire connector if i remember right. It should be mounted on the passenger side strut bubble inside the engine bay. Between the battery and the strut bubble and between the under hood fuse box and the engine. It is held on by two 10mm bolts. I know that this is where the voltage regulator is on my 1985 Honda prelude with the 1.8l carbed engine and since the 84-87 were mostly the same it should be the same on yours.
is inside the alternater
Most vehicle manufacturers now put the regulator inside the alternator.
just follow the positive line coming from the battery. The first component it meets should be the voltage regulator.

The 1986 Honda prelude 2.0 Si has a A20a3.

The voltage regulator/rectifier is mounted on the battery case.
The voltage regulator for a 1991 Honda accord is mounted on the rear of the alternator. It is bolted on and can be replaced as a separate unit.
A 1994 Honda Prelude S would not have a VTEC engine in it (assuming it has the original engine in it). It should have the F22A1 in it which is SOHC and Non-VTEC.
Yes, All H and F series engines are interchangeable.
You could, but because the '94 Prelude is heavier than the '89 Prelude, it doesn't make sense to swap in a smaller powered motor.
In the alternater!
Inside the alternator
Yes. The H22a and H23a motors can interchange transmissions.
Have the car taken to Authorised Repairer for the Honda Cars. They can find out what has happened to the engine.
How can I check the ENGINE COOLANT TEMPERATURE (ECT) sensor on my 1991 HONDA PRELUDE SI 2.1L
The starter on the 1989 Honda Prelude is located on the left side of the engine. It is under the radiator hose that is at the rear of the radiator.
The horn on a 1987 Honda Prelude is located behind the front bumper of the vehicle. It is mounted in front of the engine block.

H22A Honda engine it ready for a turbo
1990-91 Honda Prelude Si, not the 2.0si
As far as I know this regulator can be used on several other 4 cylinder Honda motorcycles of similar engine size, from the late 70's models to the 90's models.
