voltage regulator
I was checking out some splices and grounds and came across some kind of resistor spliced into the black solid wire on the voltage regulator and of course it broke. Is it some kind of static eliminator? The #'s on it are IX4004 Gp 0324A. Just wondering if I can eliminate it for now. Thanks, Vinny

Also instead of going to ground there was a capacitor just wire tied to the harness. I should be able to set it back up to stock, which I'm kind of guessing that, I can solder the connection together that had the resistor on it and make up a new ground wire and eliminate the capacitor. Yes, maybe?

I found one schematic for the wiring doing a search. Most of the threads are now dead. The schematic and post were helpful but, it showed a connection that I can't make out and in the post. I just would like to be sure before I do it. I can't afford to burn anything up.

The only black wire on a '64 voltage regulator is a ground wire screwed to the base of the regulator to under the head of the screw that attaches the horn relay to the radiator support; there is no external resistor anywhere in those circuits. If the car has a radio, there's a capacitor screwed to the base of the regulator (under the same screw that attaches the ground wire).
Do you have the '64 Assembly Manual? The voltage regulator ground wire is shown in UPC 6, Sheet B4.00, and the radio capacitor on the voltage regulator is shown in Section U69, Sheet 7.00.
There's also a complete wiring schematic at the end of Section 12.

The black ground wire that connects to the regulator underneath was solely connected to a capacitor that was wire tied to the harness and not grounded to anything. the wire that was spliced with the resistor I think it was black with a pink stripe and was on the # 4. The alternator black ground was connected to the radiator support. Anyway I made up a ground wire and spliced the #4 together and now She's not charging. Before she would charge but, when I put on the blinker the gauge would bounce all over the place. I pulled the regulator while the car was running and checked the output from the alternator and it was not steady, mostly just a few volts and occasionally around 14.5. I have the kid running over to CAP to see if they will bench test it. I did kind of screw up taking the regulator off. It's just under a relay and the plug in was in the way so I pulled it off to get at the bolt and shorted it out while taking the reg. off. It was only for a split second. I'm still getting a few volts there. So I hope I didn't damage anything else. I did find a wiring diagram @ free chevy wiring diagrams and I did not see anything that resembled what was there so I figured that it was O.K. to eliminate it.

They say it was bad. So I bought another one. I started her up and the ammeter as at 0. I dis-connected the ground on the regulator and re-connected the capacitor. Now the gauge is all over the place for few minutes and then calms down. I'm just not seeing why it's not working out. My brother had three other alternators but the plug in on them is different than the harness. Wrong alternator, wrong harness? What voltage should I be getting at the alternator? It's still not consistant. A few volts and then 14.5. If I had a dead short I would think that something would fry and I haven't seen or smelled anything.

Not sure how they did it in '64 but this is the capacitor connection on the voltage regulator for a '66.
As you can see, the capacitor plugs into the #4 terminal. I would remove all the capacitors. If they are original, they probably don't work anyways. And they can short out causing more grief. They only help repress radio static.

Hope these come out. It shows no capacitor and that terminal goes to ground.

Here are some pics of the alternators I have found. Which one is the right one for the car or does it matter. Right now I have the one on there that matches the harness. What could be making the gauge screw up? It flies all over the place on start up and the calms down after a few minutes.

When I was searching through some of my pictures I found this one of the family. My brother that owned the car "Franny" has the hat on. I'm the one on the left. Youngest of six. Motley crew, heh.

The wiring diagram shows no capacitor because it is for the radio, which was an option.
Here is a pic of an internally regulated alternator.
The terminals are marked 1 and 2.
Externally regulated alternator terminals are marked R and F.

Plug in's do not match from one to another. I believe. I put on a new one, same as the one on the car when I got it. But my brother had a box of old ones that look like your pic. That's not what's on the car. The one I put on is a three wire not a 1 wire and said it was external regulated. It was only 42 bucks, So I'm pretty sure it is not internally regulated. I don't know what these other alternators where for and can't ask him where they came from or what they where on. Sounds like your yelling at me Z, cut me a little slack please. It's hard in more ways than one to work on my brothers car. My father and brother were the car guys to talk to and they are both dead. My brothers was soon to be ex wife before he passed away kept all my fathers and brothers tools and I just haven't messed much with old cars for over twenty years and even then it was just to keep them going. Thanks for the pic though, that's what I have except the reg. is on the rad. support.

Talked to MSD and they said That the problem should be solved with one of their noise filters. Hopefully it will protect the amm. gauge from going crazy on start up. It mostly goes away after the car warms up. I guess I'll find out.
