Alternator not charging
You HAVE to have a regulator, it looks like this:
unless someone removed it. Find it, remove it, scrape the firewall and mounting flange and remount, making absolutely certain it is grounded.
If that does not fix the problem, make a couple of quick checks
Pull the green field wire off at the alternator, turn the key to run. You should measure battery voltage at both field terminals. Now take a clip lead and ground the alternator terminal which is now unhooked. Not the wire---the alternator terminal.
This will send full 12V through the field to ground. Now start the car and bring up RPM and see if it charges.
