IĀ“ve posted a question on my charging problems in another thread and got some good answers that led to ordering a new alternator...Now IĀ“m thinking about changing to a internal regulator style instead of the external type IĀ“m having now, mainly because my speedshop carries the internals in stock and the external one is on order and I want to fix it a.s.a.p. instead of waiting...
How do I rewire if I go this route?
I found a schematic on the net but is it accurate?
HereĀ“s the description...

Pit Stop with Marlan Davis
Here is how to wire up a 94-amp 12SI on a '70 Chevelle/El Camino using a new 8-gauge charging wire from the horn relay to the alternator BAT terminal. Reroute the original 10-gauge charge wire to the junction block near the battery; combined with the original relay-to-terminal 10-guage wire, this effectively equates to upgrading this circuit to an 8-gauge wire, but doesn't disturb any of the factory in-harness splices. The external voltage regulator splices apply to most any GM cars with an external regulator.


As I see it they suggest that I splice the two outer wires on the regulato together and the same goes for the two inner wires. Then put a new + wire from the horn relay to Bat on alternator!
It states that I should take the original bat wire and route it to the junction near the battery? IsnĀ“t coming from there already?
A lttle confusing for me but solvable I guess...Any good easy tips to do this conversion, a pic would certinally help!
Thanks again!
PS! Is there any advantages of this conversion?
If it seems to hard to do I may wait for the alternator with the external type...

Attached is the schematic of how I change to the internal regulated alternators. It is simple and easy. (I don't use a ground wire as the alternator gets a good ground through the mounting to the engine. wire 12B).

Jim,

Are you 100% certain about the jumpering at the old external regulator plug?

The reason I ask, is that I made the external to regulator swap about a year ago, and I happened to be looking at it yesterday.

I have the blue wire (from the alt) jumped to the brown wire (to the dash light), and then the center two wires jumped, (mine are red and white, not red and black as you show. They are the center two positions on the regulator plug. My car is a 1967, but I think it is the same.

I bought the kit and followed the directions from MAD Electric. At least I think I did.

I am looking for my directions now, and I can't find them, Back when I did this, I thought I understood what I was doing. But maybe not. The car has been working just fine, with good charging and normal ops and no smoke yet.

dwg2116: That way you have it is like the description I posted, at least on the jumperwires and there colors...

You are right to question the schematic. The schematic does not match what I do. I did not look at it closely enough when I posted it. Attached is a pic of my 66 jumper wires and they are the same as the other (11) vehicles that my boys and I own. (A couple more of our cars still use the external regualtor).

I deleted my original post since the schematic does not apply.

Ok, it looks like the "jumperwires" is like my original description that I found on the net but how about the main cable to Bat+, can I leave the one I have on there and just put the splice on the regulator or do I need to change something on the main cable too? Where does mine come from? And if I need a new one from the horn relay as the description above says, what do I do with the one I have on there now?
If I understand the description above it suggest that I put my original Bat + wire back to the junction block but isnĀ“t it already going from there?
On the horn relay I already have 4(I think) big red ones...

This is what I used as a guide when I changed mine
These are the directions from an adapter kit my friend used on his car.

I didn't use the adapter.

On the existing connector you can either install a jumper (as shown)or cut the wires and connect the 2 together that the jumper would have connected and cap the others.
At the alternator I changed to the new style connector and capped of the un used wire.
and installed a jumper from the output.
with the new style connector at the alternator it looks clean too.

It works great
Hope that makes sense

Thanks for the tips my friends!
I printed them out for future references!
Today itĀ“s wednesday and my new alternator arrived, I didnĀ“t bought the internal type, I bought the external type for a test, my Speed shop let me change both the alternator and regulator for a new one with internal regulator if I want!
Everything is mounted but it still troubles me some, I posted the problems in the other thread about charging problems, check it out if you have any ideas...
Thanks once again!

Problems solved(I think...), for info on what I did, look at my other post about charging problems...
