high voltage stock 6.1 alternator

you mean disconnecting one field wire? Isn't this terminating the regulating function and raises the voltage while engine running? I don't have a PCM, I have old School wiring..

my idea is sensing voltage close to the battery or start Relais ( both in the trunk ) but know i noticed i Need switched plus and not permanent plus like it is at the start Relais. I can only sense at the ignition Switch or fuse box ( which is now from a E30 BMW hahaha... bunch of obstacles )

Or last idea: It is simply the VR which is designed for 60A alternators and not the 190A HEMI sucker...
