George ... you nailed it.. thanks to Bartamos input on “ if a wire goes from battery to alternator it should measure the same voltage anyplace you measure it “ got to thinking I never checked the voltage on cable conecting to altenator. I disconnected wire from alternator turned ingnition on and got zero volts on cable checked it at ammeter and had 12v the wire had heat shrink around the lug term and the wire slipped out the crimp on lug .. I don’t have the correct lug to recrimp and terminate but I’m positive that is my problem 🙄.. something so simple thanks for every ones input ..
