My 70 GTX stopped charging

[Johnnyscarnuts]

Can use some help to test and figure out what to change
Voltage regulator???
Can someone help test?
I’m actually more of a part changer honestly, the only alternator they offer is a power master 90 Amps but how do I know that’s it? it does read only 11 1/2 volts maybe regulator?
Thanks in advance

If it is the alternator, it's usually the brushes that go bad. They are very easy to change. CX1T is the part# for the brushes. You can find them online or at a parts store.
One more question. What is that exposed fuse at the bottom of the alternator picture? Not normal.
