Have you made sure you don't have any broken wires and the alternator is grounding correctly? You should have zero resisntance between the body and alternator casing.

well i check the plug to make sure no brokin wires and tomarrow im going to try to play follow the wire " everyones favorite game" haha and figure out where they go but all i no by looking at it is they go behind the motor somwhere
You need to verify the connection between the battery positive terminal and the generator output using a volt-ohmmeter. You could have an open fusible link. Just a point of information...the PCM is not the regulator. It does send a turn-on signal to the generator when the engine is running, but the regulator itself is contained within the generator.

^^ he is right on. The easiest way to check for the broken wire is to do what is called a voltage drop test. To do it get a volt meter (digital perfered) set it to the correct scale (either 12 or 20 volt depending on the volt meter) put one lead of the volt meter on the stud of the altenator where the battery cable attaches and the other lead on the POSITIVE battery terminal. Be very sure you have your meter set to volts other wise your gonna have some sparks and prolly blow a fuse in your meter. Your reading should be less than 1 volt. If you have any thing higher than that your connection between your altenator is broken (either the wire is cut/corroided, or the fuseable link has blown)
That should tell you what is going on, if you need anymore help let me know.
