Everything worked as it should the first time. I'd recommend American Autowire to anyone who wants to update their wiring. I called today and spoke to one of your Technicians. I had purchased one of your engine harnesses for my Chevy II Nova and the light harness.

I did all the wiring as described, but had no power throughout the car. The Nova still has its original wiring except for the cables I upgraded with American Autowire. Well that said, the Technician immediately knew of my problem, and was patient with me with all my questions, as stupid as they may have sounded.

It was a simple fix that I missed during the installation. I just wanted your management team to know they have good knowledgeable and professional technical staff working for American Autowire!The Jalopy Journal. Terms of Service. Privacy Policy.

The H. Luis 94 blazer likes this. That is the best I have seen. Very self expanitory. I assume you could also just hook the 2 wire on the alternator directly to the battery post on the alternator?

Get rid of the gauge wire and you're down to a homemade one wire alternator. You need the indicator lamp or a resistor to exite the alternator.

ScottApr 25, I didnt want to run a warning light on the excite wire and tried several way to hook it up, finally hit on a good way.This page attempts to document some of the common details and facts you need to know about when converting the existing charging system on your older GM vehicle to something newer and hopefully better. This information comes out of my research and work on upgrading my Buick Special from a generator to an alternator and from my previous work on the High Amp Alternators for older GM's article written while working on my Buick Electra.

It is not a step-by-step guide, but rather a roadmap of important things to consider and be aware of. You should read my article on Alternator and Generator Theory before delving into this as it has lots of good details and basic cautions that will help you understand the details in this article.

It's a tad heavy on theory, but once you understand why the system does what it does, then the wiring makes perfect sense and it becomes very easy to figure out what you need to do on your vehicle. The information here can be of use to someone who wanted to convert the electrical system on a non-GM vehicle, but how much of this is accurate is up to you to decide.

Ford and Chrysler and even alternators on imported cars operate on the same basic electrical theory but their specific wiring differs and may have unique quirks to it. In particular, I believe both the Ford and Chrysler alternator systems were externally regulated until well into the '80s, and neither has the remote voltage sensing feature.

There are unique issues to be aware of on each one, so I'd suggest that you go read up on them elsewhere before you attempt a non-GM swap. Or, just be like me and stick a GM alternator in it even if it's not a GM. Before actually tackling any physical wiring, you should take the time to read the suggestions outlined in my Reusing Plastic Wiring Plugs article for ways to get a cleaner appearance to your wiring efforts.

Also, if you own an older Buick with the "push gas to start" feature, check out my page on preserving this feature after you convert from a generator to an alternator. Lastly, there are many other great resources out there - don't rely only on my site. Read up, and learn as much as you can. Car Craft has an excellent page about wiring workand MAD Enterprises has some great technical details on why a 3 wire alternator is better than a 1-wire alternator as well as a great technical description of the remote voltage sensing feature of a GM 3-wire alternator and details on the various models of the 10SI and 12SI series of GM alternators.

There are three kinds of upgrades you can do. You can go from a generator to an alternator, from an externally regulated alternator to an internally regulated alternator, or you can take the monster leap and jump from a generator all the way to an internally regulated alternator.

How to Wire a Chevy Alternator

I detail all three separately, see below. Before tackling them, you should give my GM Alternator Identification page a quick look to see what the visual differences are. A conversion like this has two basic pieces to it - mechanical and electrical. You need to mount the new alternator so that it's secure and you can put a belt around it and then you need to wire it up so it actually does something when you spin it. This is a non-trivial upgrade to your vehicle.

It's not that hard, but it could take some time to get right. Don't expect to have the car back on the road the same day you take it all apart.Main Page. Click on thumbnail to see larger picture. The CS weighs less, is smaller in diameter but uses the same 6.

There is also a amp, CS version if you need more output because you're running large amounts of electrical equipment in your vehicle such as high-powered stereos. NOTE: This conversion is designed for cars with internally regulated alternators. If your car has an externally regulated alternator you will need to convert it first. Use this diagram and go to Alex Bilan's Alternator Conversion webpage for more information on converting to an internally regulated alternator.

You will need amp CS alternator from and late's GM truck or full size car with mounting ears that are deg apart photo 3. I got mine from the local PepBoys and it didn't take too long to find one with the correct mounting ears. Most will probably come with a pulley for a serpentine belt like mine did so you will have to change over your pulley if you are still using a V-belt.

The flange for the tensioning bolt and the alternator bracket are tapped for metric bolts so you will need to get two 8mm bolts with a thread pitch of 1. A 13mm wrench will be needed to tighten the bolts. The alternator bracket will also need to be modified and you will need approx two washers to take up the space between the alternator bracket and the alternator.

Photo 11 shows the modifications needed to allow the bracket to fit the CS alternator. The red line shows the original shape of the bracket and how much needs to be ground away. Most of the connectors for the CS alternators are four wire but will only use two of them and the wiring is the same as the SI.

One is a CS connector to plug into the alternator, the other is a female connector to accept the SI plug from your original harness. There are two different types of conversion adapters. One is a non-resistor and the other has some resistance built-in it. The "L" wire that energizes the alternator needs some resistance 35 ohms or more in it otherwise it will cause the alternator to fail. If you have a warning light in the dash then that bulb serves as the needed resistance and you should use the non-resistor adapter.

If you don't have that bulb or have less than 35 ohms resistance in the "L" wire then you will need the adapter with resistance built in. If the "L" wire has more than ohms then there is a problem with that wire and it will need to be fixed.Searching for details about 1 Wire Alternator Wiring Diagram?
