I got a 3.0 over head valve . Mercury sable 2002 .
What is your question?
The battery light is on in the dash . The alternator is not putting out any charge . I put a new alternator on it and still not charging . The fuel pressure is very eratic and flooding . I did replace the file pump also . All fuses are good and grounds . I checked the mega fuse also . I do know the pcm tells the alternator when to charget . A pcm is very expensive and I hear it has,to be programmed and chipped. Does anyone have any other suggestions

I just checked the cotinuity on the three prong plus and it's all good . I do have 12 v on one of those wires . Do u think the alt. Not charging is the culprit of my prob. Because this thing is acting like the pcm is not reading the correct values . That's a guess .we own a shop down here in conway . This one has got me stumped . Any more suggestions .
the regulator on that alternator is Integral to the alternator.if you have 13.5-15.0 VDC on the battery when it's running,then it's fine.if not,maybe bad,NEW alternator right out of the box.or like i stated before,lots of problems with the harness connector.good luck with it.
I found the problem . It's a bad insrument cluster . Wire comes from interior fuse panel to cluster in dash w 12 v power and comes out and powers the pcm to let it know when to charge alt. . I had power going into cluster from fuse panel and none coming out to pcm . On pin 98 green and red wire . Resolved . I would have never thought it would be an instrument cluster . Hope this helps some onev
