Hello, I am afraid that the voltage regulator is INTERNAL. Which means that you will have to replace the alternator to fix your problem. This is an under the Z job and I think it is a 2.3hr labor rate at the shop. I can do them in about 30-45 minutes. Before you do replace the alternator please keep in mind 2 things. First, buy an alternator with a lifetime warranty!!!!! There have been a few bad batches of diodes within the alternator and a few of us had to replace the alternators every few weeks a time or two. Or you could purchase an OEM one but they are pretty expensive. Second, if you do not have a set of METRIC RATCHING WRENCHES, THEN PLEASE BUY THEM BEFORE STARING ON THIS PROJECT! There is not alot of room to work and sockets just don't cut it! Believe me, the right tool makes all of the difference! You will also need a 15mm or 17mm socket and a bungee cord. It is alot easier to swing down the sway bar but before you do lash it up with the bungee cord so you don't hit yourself on the head :) You will also have to remove the skidpads underneath and don't be heart broken when you will snap off the heads of a few 10/12mm bolts. This happens! You do not need to remove your alternator belt but clipping it out of the way helps. Also, YOU NEED TO COMPLETELY DISCONNECT YOUR BATTERY!!!!!!!!

Located in the back of the engine on the driver's side next to the O2 sensor connector.
Normal operating voltage should be close to 13.5. If you're only getting 10V, you need to replace the alternator and/or regulator. I'm not certain but usually the regulator is inside the alternator. If you can drive the vehicle to an auto parts retailer, you can probably have them test the charging system for you.
Hi there All vehicles have a regulator, in the past it was more common to have a separate unit but most vehicles these days have a built in regulator in the alternatorOn Nissan vehicles some models have an external regulator and some an internal. Hitachi and Mitsubi alternators are used. To identify which one you have, (if the id stickers are missing or illegible) is to see how many wires come out of the unit. The alternator with a separate or external regulator has about 3 or 4 wires leading to it. One thick one for the main charge and then two or more thinner ones for the field wire and earth The units with the builit in regulator have only two wires. One for the charge light and one for the supply.I hope this is of help to youregardsRogueYou can visit this site which has an on line manual http://www.300zx-twinturbo.com/cgi-bin/manual.cgi?list=el&dir=&config=&refresh=&cycle=off&scale=0&design=default&total=133
They are located directly on the turbos. 300zx have internally wastegated turbos
The vacuum modulator on a 300zx should be located on the rear of the engine. It is on the passenger side at the top, close to the firewall.
Where is the ignition control module on a 1987 nissan 300zx
it is located on the side of the transmission
On older 300ZX's equipped with a timing belt it will cause internal engine damage if the belt breaks as they are interference engines.
The windshield washer reservoir in a Nissan 300zx is located behind the rear left trunk panel inside the trunk. This is where it is located in my twin turbo anyways.
I would suspect the fuel pressure regulator.
next to the transmission
it is located on the transmission itself
