REALLY need help wiring in a CS-144 alternator

[gmachinz]

Yes....on its own, that wire should have 12V on it with the key in the "on" position. If not, just try using a jumper wire from the "I" alt terminal to the battery and measure output alt. voltage-you may need to run the remote sense wire to the battery too just for testing purposes. Now start the engine and verify you have over 14V coming out of the alternator. If you do, go through your existing wiring by tracing the brown lead. If you don't, then that alternator has an issue. It can be tested at a parts store just like any other CS type alternator.
