I installed a 80-2SC on my 2013 Cadillac EXT. The alternator does not work as it needs some current to excite it. I have looked at the units that have an "Energize" connection but the wiring diagram shows it connected to the alternator at a connection other than B+. My alternator only has the B+ terminal. Can I connect the it to the B+? Ideas on how to make this work?
