Default 94 sc400 giving low voltage need help!!!!

Hi everyone, so I just got a 94 sc400 and it runs great but my alternator it's only giving 11.58 voltage so I got it rebuild alternator that works I even got it test and it works so after I got new battery, alternator fuse, and I even put a extra ground wire thinking that it would help but the alternator is still not giving enough voltage to charge my battery. So if someone know whats going on please help....

I had a similar issue with my sc300, I change the alternator, battery, removed and cleaned my ground cable from the battery..12-13v would show at cold start but as soon as it warmed up it would drop to 11v.. It ended up being the power cable to the fuse box next to the battery which created resistance.. I cleaned the copper looking contact and full voltage was restored...
