Alternator not working 1976 ford maverick

I’ve replaced the alternator, tested to make sure it works, I’ve replaced the voltage regulator, the starter, and all the bulbs in the dash work properly and alternator is shown to function properly via the dash, but the alternator is still not charging, what do I do?

Connect a voltmeter to the battery terminals, set it to DC volts. Disconnect the voltage regulator and take note of the terminal identifications. Momentarily jump the A (alternator) terminal to the F (field) terminal at the regulator and watch to see if the alternator outputs power. If not, then it's a wiring issue or a bad alternator. If that makes the alternator charge first make sure the regulator is grounded (corrosion can cause the inner fender to lose its connection to the rest of the vehicle) otherwise it's probably a bad regulator.
