Contemporary Specific wiring question
 
Ok folks, shaking down the Contemporary Cobra these past few days, I noticed that the alt. was not charging, checked everything over, yet still not putting out anything. So, I go to grab it off the engine, having just noticed only one wire feed off the postive side of the alt. (no other wiring harness connections at all) Now, I know all about one wire alt's, but this has me puzzled, as there is a three wire, slim box on the back of the standard Ford alt (that I have never seen before in my life), that seems to be part of this setup............What have I got on my hands here folks, and what can I do to swap it out for something a little more simplistic...............



Yours in wiring handicapped Fords,

All the one wire Ford alternators I have seen have the self exciting regulator mounted on the back of the case, not built in.

Will yank it back off and post a picture in the AM to see if we are indeed speaking of the same item...Just something I have not seen in my normal Ford travels over the years.........

mrmustang,

That appears to be a "Self Exciter Regulator" as mentioned by Specialk, I have a similar one on the back of mine that I added when building it so that I could run a single wire to the alternator and not have the external regulator box on my firewall. If this is bad, your alternator will not work. Take your alternator to a reputable Automotive Electrical component shop and have them test it, they should be able to tell you exactly what you have and whether or not it is working. I did this when converting to the single wire just to make sure of what my alternator was putting out (amps wise) and then they had the "box" in stock for $28.00 (I think). If you don't have a good shop like this in your area, I can probably get you information on where to ship it here in the Fort if you're interested. Just let me know here.

It's a conversion from a 3 wire system to a single wire system.
I also have it on my car. Be sure you unplug your voltage regulator, it's not needed with this set up.

Now if they will ship it to me overnight, I'll be in good shape........
