1995 Ford Contour ALTERNATOR

OK, You say you have 12 volts coming down the grn/blk wire with key on. That's good.
The red wire from the fuse block, alternator term A, should be 12 volts at all times. YES?
Red battery at the alternator, B+, should be hot at all times. YES?
Grey wire should jumper from alternator term S to term S. YES?
If you can wiggle the wiring harness at the alternator, but it quits when you turn the car off, you're losing the connection somewhere at the grn/blk or the gray wire where they connect tothe alternator. I would look closely at the grn/blk conn. If this wire is bad, the wiggleing may make momentary contact to charge the fields of thealternator. It will keep charging until you break this connection, ie. Turn the key off. Hope this helps.

According to my schematic there are 2 red wires going to the alternator. One from the battery, " B+", and one from the underhoodfuse block, "A". "I" is grn/blk and "S" is grey. Does this not match what you have? Let me know.

According to my chart;
Red = 2, Blk = 0, Red = 00, Gold = + or - 5%
That's a total of 2,000 ohms. Wattage just indicates how much load it will carry.
If, with the car running and you unplug the alternator, is the dash light(charge) come on? If yes, put 12 volts to the grn/blk wire at the alternator connector with it still uplugged. Does the dash light go out?
If you have, or have access to, a fax #, I'll ship you a copy of my diagram. This way we'll both be on the same page. Let me know.

By "0" resistance, do you mean you have continuity through the grn/blk wire, or the wire is open, no continuity?
If you run a test light from the battery + to terminal "I" on your alternator it should charge. Also, if you ground terminal "I" the dash light should come on. Let me know asap. It's midnight here.
The diagram I have is from the Mitchell library.

Check to see if you have 12 vols, or close to 12 volts ay the connector end of terminal I. If you don't, you have an open between connector twerminal I, and the fuse in the interior fuse block.
Grounding terminal I at the alternator connector should light the das light with the key in "on" position.
There is a "resisting diode" in conjuction with the dash charge light that allows fuse block voltage to run around the charge bulb to allow reduced voltage to bypass the bulb as it goes to the alternator. When the alternator starts to charge, it sends voltage back up the grn/blk wire and with 2 positive feeds to the bulb, it goes out.
Do you gave a "grey" wire that loops in and out of the alternator? If yes, make sure these connections are good. Let me know.

I'm sending you a shot of the diagram I'm using. I'm trying to dig up a schematic for the internals of the alternator itself. I'm thinking ourproblem may be in the Grey wire circuit. Let me know if you don't get the diagram as an attachment.

This diagram didn't come very well, I'll try another.

The attached looks like the voltage regulator is a screw on unit. I can't get a very good shot at it. Take a look at yours. This could very well be our problem. Let me know and I'll keep looking for an exploded view. This little project has now become a personal vendetta.

Glad you found it, chief. I love it when a good plan comes together. Anything else, you know where to find us.
