On my 7.3 i had to replace my alternator , I also replaced both batteries. I had the same thing happen.What i did was i had to run a new hot wire, that turned hot when the ignition was turned on, the alternator then charged. I used the wiper hot wire. was the shortest and i didn't have to run a wire into the cab.
The only problem I have now is it doesn't put out a charge right away.
and when idle it doesnt put out 14 volts only when i rev it up past 1000 rpm will it then put out a charge, I only run into a problem with this set up is when i have my heater fan on full , and or lights on .
I havent had a chance to take it in to a buddy who deals with auto electric
but if it is a problem i can post and inform my finds, if no problem or finds then i wont post anymore,and i would then say assume things are OKAY
