70's style alternator in my 65
 

Whats the bast way to wire a newer alternator in my 65 ? Do I need still need a voltage requlator ? I've heard that the newer alternators have a voltage regulator built in. Is this true ?

Thanks for your help.

Give that a shot, lots of good ideas.

I just put a new model alternator single wire on my truck. It depends on what model alternator you get on how to hook it up. Find one that is newer and has the model number still on it then you can figure that out really easy they only come in a few different models actually. Be sure to grab the connector to goes from the alternator into the wiring harness as well so you dont have to buy that. PM me if you have any specific questions.

It's definitely worth doing, my headlights are probably 20% brighter now and it cranks quicker as well.

So do I get rid of the voltage regulator ? If so what do u do with the wires going into it ? Thanks for the help

Re: 70's style alternator in my 65
 

If you use a single wire alt, you dont need a voltage regulator. As far as the old wires to the alt, just tape them back or cut them away. You can convert any style atlernator to a single wire set-up.

you want a 3 wire-

The alternator I have has three wires. I just need to know where they need to be hooked up and I am assuming I can ditch my Voltage regulator. Any help on where to hook these three wires up would be great.

Here is how it looks in a similar gm arrangement, the black and white stripped bar is the firewall.

Re: 70's style alternator in my 65
 

The easyest way I think I can tell you is get a 3 wire. On the 2 wire plug the terminal furtherest away from the battery wire goes to your charge light. The terminal closest to the batt wire needs to go to the batt wire terminal. Then your main batt wire goes to your battery. You will ned to upgrade your brackets to the year of your alt. If I was unclear let me know and I'll get you pick of mine. I have a 80s alt in my 65 useing the original charge light.

Thanks for all your help! Thats what I needed!

Re: 70's style alternator in my 65
 

I did the conversion and it works great. No more regulator or dimmed lights at idle. Here are a couple of links I used to figure it out.

I didn't need to buy anything other than the alternator.

Did you have to cut your exhaust manifold for it to fit?

Re: 70's style alternator in my 65
 

How do you decide which alternator to ask for at the Parts store? It seems most articles are geared toward the one that would be used and have bracketry for a v8. I am trying to figure out what to use on my 250 six cylinder.
Thanks!

Re: 70's style alternator in my 65
 

The one I have dropped right into the old spot on my 250 inline no bracketry to fix or anything and my old one was the original one I think!

If you are scared of wiring, you can alway buy this for $18 it seems like. http://www.truckandcarshop.com/trucks60_72/t60_105.html It is the Alt conversion kit. Basically plugs into your firewall plug and you just hook it up to the alt.

Do you know what vehicle the one you have was listed for?

you can call these guys and give them your application(the number off the old one) and tell them what you want to upgrade to and they will give the nbr for the new one

Here is the page I found my information.http://www.extreme4wheelin.com/tech/...ators/tech.htm
I have the CS130. This was purely by accident, I was walking around the yard and saw it laying on top the engine already taken out of car/truck apparently. It looked brand new so for $15 it was mine, simply swapped out pulleys to the V groove, took it to Kragen for testing and installed it.

Re: 70's style alternator in my 65
 

I just told them early 80's 3 wire and they new what I was talking about.

Re: 70's style alternator in my 65
 

Jason65,

My alternator mounted just as before. You need to buy one that is "clocked" like the one you take off, that is the housing is rotated properly so that the plugin and the mounting ears are in the right position.

I was changing to a serpentine belt at the same time and had to make some spacers and get longer bolts to line up with the pulleys.

I moved mine for headers. Are you useing rams horns? What year of alt did you use? I belive the Delco 10s1 is what I ran.

Re: 70's style alternator in my 65
 

Jason65,

I used a CS130 from a late 80's truck. Mine mounts to the rams horns.
The CS130 is just a later model, higher output. They go 10SI, 12SI, CS130 ...

Here are a couple of links on the CS130 conversion.

I run a two wire setup (Big hot wire and one small wire for voltage detection). The second wire lets the alternator monitor and control the voltage out at the main junction. The single wires just see the voltage at the alternator output. At least that is the way I understand it not being a sparky.

Jason 65,

Here is my setup, or was, I am engine swaping now.

Here is mine. I was wrong on an earlier post. The wire furthest goes to pos. Closest goes to gauge or light.
