Fusible link or not?

Thanks @Mattax for the thorough explanation. I will work on this after getting it running. That seems straightforward enough. The alternator that I am using is internally regulated. These are the field wires that are being used. Pigtail harness for Denso 210-0106 alternators | AR Engineering One wire is the feed from ignition and the other is the 12v sense wire. I have them both hooked up to the distribution panel. Should I take the sense wire and connect it elsewhere? Directly to the battery? Seems to me that it is sensing the same voltage , or close to it on the panel.
