Bad Alternator??
Thanks, the previous owner changed out the original alternator n changed the wire to internal. The alternator is different from your pictures. Here is the back of my alternator n I will get the front later.
1.........Make absolutely certain you have "a" correct alternator and that the field is not shorted. You should have TWO field connectors, and a blue and green wire hooked to those connectors
2..........Determine if the regulator has control of the alternator. To do that, unhook the green field wire, but leave the blue one connected. Run the engine, and run the RPM up and down a bit. Voltage should be below 13V
Your alternator should look something like this:
This is an older design, but it is till made in 70 or later, and has TWO field terminals
The one on the left, below, is a later 70's so called "squareback" and is a better design. The one on the right, below is NOT what you want. It only has ONE field terminal, the other being grounded.
