About the SELF EXCITATION............what I mean is that there is residual magnatism in the rotor of the alternator and if you spin that sucker up high and fast that that residual magnatism will cause the alternator to self excite and put out. I don't recommend leaving the white/black off, just saying that a series four will put out without the white/black excitation wire being hot.
Some people say that you can run switched voltage to the white/black wires contact on the alt and things will be fine. I differ a bit on that .
Again.........whether or not the alt relay ever pulls in or not matters not. As long as the METER fuse (or other switched power fuse power) goes thru the COIL of the alt relay to the alt is what matters. It is INDEED looking for a ground to cause the alt relay to pull in and tell the driver the alt is not working.........but that is NOT the main reasone they have power going thru the white/black to the alternators field. It going there to excite the alternator so it'll put out.
Ah heck. Run a switched power to the white/black and have at it. The alternator will put out...........but if it were me........I'd run a wire from the white/black at the CPU plug to the alernator and make the system as factory designed. I mean you NEED the CPU anyway.
This a turbo or non turbo car??????????
