ok so this is what im going to do.
1. I have 14-16ga from fuse box to a power souce only when I turn the key.
2. Connect that wire from the fuse box to the white wire on the stock pigtail, replacing the brown wire that i have bad?
3. Plug in our stock pigtail red/white wire to the ES82 connector and then that into the alternator.
4. Start the car with meter conneted to see if im at 14-14.5 volts.
Well from your pictures it seems the red wire on the stock pigtail is what plugs in to the field terminal on your alternator. This needs to be any 12V power source as the alternator cannot convert energy without.
The white wire seems to be what plugs into your sense terminal on your alternator. This wire just needs to be at system voltage so it could be connected directly to the battery post on your alternator. This is not the ideal situation as it will not regulate the voltage properly. Instead, it should be connected to the positive terminal of the battery or somewhere farther away in the system. Your proposal to hook the white wire up to an ignition switched power source should work if everything else is connected correctly.
The sense wire lets the alternator "sense" the actually voltage in the system and boost it to the proper level.
So you should have:
1. A connection directly from the positive post on the battery to the battery terminal on the alternator
2. The connection you already have to the red wire on your stock pigtail
3. A connection from anywhere in your system that sees full power (i.e. battery, fuse box)
As far as I can tell your proposal should result in a working alternator. If not, I'll try to offer any further help I can.
