Need quick information about alternator connections !!
Hi there
Right at the moment I try to figure out how these alternator wires were connected. There are 4 wires.
One fat red one that routes the juice to the battery, one fat black one the housing that gives connection to ground.
And two wires that end in a plastic connentor, which is unfortunately damaged.
I think this connector goes to the regulator (at least it looks like that the regulator is part of the alternator in my 76).
The problem is that the connector is broken and both wires are out of the plastic connector. Now I don´t know which wire goes to which connection.
There is a brown small diameter one, and a red one.
If they would be still in the connector I would´t have a problem because the connector only connects in the right position.
Would anybody be so friendly and send me a picture or describe where one of the wires has to go?
Thanks a million, Markus

This is a service replacement part. The white is your brown.
Another view that I just picked up from my archives.

Also to add to Pauls post, the little brown wire goes through the firewall to your generator "idiot" light and to pink/black to your fuse box.
If this wire is not providing 12V from the fuse box through your Generator light and back to your alternator, then you will not get any 14V power from your alternator. It supplies field windings with excitation current.

Hey, thanks for that info.
That helps me alot.
The privious owner messed up the harness, so I try to repair it.
The front with the headlights, horn and everything is already done.
Wish me luck.
But I have a feeling that my knowledge gets more and more the longer I work on these harnesses. I already now where and how to measure to find out all the different wires.
Too bad that the marks on the insulation tape of the wires bleeded out. I can hardly read them anymore. so for the futere use ballpointpen and not these fancy foilmarkers.

I guess you are almost finished but I would have been tempted to just replace the firewall-forward harness.

Marcus, on the regulator wiring, the one with voltage on it all the time, is the alt sense wire, from the main tie point on the horn relay....it goes to the MOST CLOCKWISE reg terminal viewed from the REAR of the alt....., the other wire goes to the other term, and is for the light on the dash....if your car has one....varies from year to year....
OK, the sense wire determins the charge rate, and is allways hot....
the light wire is hot ONLY when switch is in run position....
the power for the field windings runs through it's own dedicated diode stack inside the alt, into the regulator into what's known as a 'pass transistor' and then into the rotationg field assy....the amount of voltage/power into the field assy determins the amount of magnetism and thus the power output of the alternator....
