do you mean S on the harness? how do i test the reg. with it plugged in?
I don't remember if the harness connector is labeled with the terminal letters or not. It will be the LG/R wire on the S terminal.
Are you looking at page 22 of your EVTM?
You can try back probing where the wire enters the connector.
With a test light that has a sharp probe, you can pierce the wire insulation.
You can unplug the connector. Recommend disconnecting the negative battery cable while unplugging and plugging the connector.

ok.  Well i know where the fusable link is. it doesnt feel too squishy, but i cant think of a problem other than this, now that ive basically gone through the whole system.  I ran some basic diagnostics on the wires when my buddy was here with a power probe, but ill have to wait for him to come back to finish testing everything.  that diagram was super helpful thanks.  The volt. reg. is labeled as well..... ill give this all a go as soon as i have access to the proper tools....and I'll post results.....thanks a ton.

Here is an old school no fancy tools test.
With a screwdriver, feel around the alternator case for a difference in magnetism between key off and key in run. (don't start the engine)

i am positive that the alternator is not charging. with the car running it only puts off 8 volts.  just trying to figure out where the drain is.

Is this measured at the battery terminals?
What does it read with the engine not running?

Sounds like a battery with 2 dead cells.

the battery is fine, i guess im going to take a shot at the fusable links today.  I suck with electrical so wish me luck!  I'll be back on when I figure out what is going on

Fuseable links are easy. Just probe the wire before and after and do a resistance check.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.
