got a box of stuff at auction ,. one thing is a alternator marked :63 chevy ",,. loox like it has 2 power posts ,,shux .i was hoping for one ,. lol ,. i guees it will need a voltage regulator,.. can anyone familiar with such , teach me how to wire or what componets i will need to make this alternator work on a 12 volt 430 case , Diesel ,. Thanks jim,.
 
Here is a diagram, not a real good one, but it should work if you decide to go this route.

But I am going to try to talk you out of it because...

1. It's a lot of work, a lot of wiring, a lot to go wrong.

2. You will need to go buy a regulator. All new regulators are less than desirable quality aftermarket imports.

3. You don't know if the alternator you have is any good without testing it.

4. While you are at the auto supply to have it tested, just trade it for an internally regulated alternator. They are very reasonably priced, simple to wire, lees to go wrong.

One other thing, the old alternators tend to be low amp output. It should say what amp it is, if it is the original case.

The newer ones are available in higher amps, up around 70 amp would be better.
 
I'm not going to talk you out of using an external regulator either....well, I guess I will.
You'd be better off buying a $35 internal regulator from the parts stores and going that route, UNLESS you want an application to be exactly as it came exactly from the factory.
 
Sounds like a Delcotron model DN with the plug in back instead of on top. Was introduced around 1962. There are new external transistorized regulators that are better then the original mechanical regulators that Delco used..

I am not sure why you'd want to bother if just for a tractor. You can get a newer Hitachi or Delco with an internal regulator for $25 at a junkyard. Sometimes brand new for $60-$70.

My Ford 641 has that first model Delcotron DN on it. Regulator was not working when I got it. A new transistorized regulator cost me $18. I would not spent much more then that to get that DN working.

Max output can be 37 to 52 amps. Plenty for an old tractor. A transistorized regulator is pretty essential though if you want it to be reliable.

1963 was the first year that GM used alternators in passenger cars.

Your alternator if, indeed a 63, will be, IIRC, a 36 Amp unit, and will require an external regulator.

If mine, I would sell it, and buy a later model, internally regulated alternator for use on a tractor. Someone will buy yours for restoration purposes.

In 1963, three alternators were offered as GM options. 37 amp for $5.87. 42 amp for $22.62. 52 amp for $29.30.
 
All this talk about "not worth it?" I suppose that is an individual choice. If you already have a 10DN Delco and all it needs is a regulator - $20 or less and you have something just as reliable as the newer SI or CS series.

I have a 52 amp 10DN on my Ford 641. It was on it when I got the tractor. I had to put a new regulator on it 10 years ago and has worked fine ever since. In my case - it was $18 or so - well spent. The external transistorized regulators are just as reliable as the later internal ones.

JDEM,
Do you know if anyone makes transistorized regulators for generators, like older Delco units? Or is such a thing even possible?

GM cars factory-equipped with air conditioning were available with alternators for the late 1962 models. Delcotron could be ordered in many GM cars as an option for late 1962 production jobs as well. All 1963 GM vehicles, including Corvair, were equipped with Delcotron alternating current generators as standard equipment. My '63 Buick Electra has factory air conditioning and is equipped with a 61 amp Delcotron. It has been reliable. Both the Delcotron and the regulator are the ones put on in the factory when the car was built.
 
My Chevy catalog for 1963 shows all the Delcotrons as options. That goes along with the 1963 Bel Air I had with a straight six, three on the column, and a brushed cast-iron generator. Hard to forget since the charge light always came on at hot idle.
 
I have never seen a transistorized regulator for a brushed cast-iron generator. Cannot say I ever looked
either. I assume it would be a lot more difficult to make then for what we are calling an "alternator." I
say that because the regulator for a generator carries charge current (if my memory is correct). The
regulator for an "alternator" has no charge current passing through it.
 
Also the front housing and rotor from that 10DN is the same as a 10SI with built in regulator, so if nothing else, it has some value as parts for the more modern internal regulator alternator.
