Charging Issue
My voltage on the battery is 12.2 the voltage at the ignition post on regulator is battery voltage as well as the output on the alternator. This of course drops slightly when key is on.
With the car running and i test the field wire on the alternator it's at .10 volts same for the regulator.
Just to be sure.
0.10V is what you are saying when you say .10 volts right. Rather than 10v which I would expect on the field wire, whether at the VR or at the alternator field terminal
All the measurements I asked you to get should have been done with the engine running. Was that so?
And as posted earlier photos help so much it's not even funny.
Example... If you have a rebuilt alt and you bought it for a 86 barracuda, it should be a single field wire round back alternator. But the supply of round backs are small so most rebuilders just convert a square back to run as a single field wire alternator.
Now if the rebuilders goofed and left both field terminals on the square back isolated then it would not work in a single field alternator setup. (Without modifications) a photo of the back of the alternator would help to determine if the terminal was properly grounded.
You can also use an ohm meter to test both field terminals with the field wires removed one should be direct short to the case, one should be at some number of ohms ( in the 10s ohms IIRC), if both are OL (infinite resistance, or Open circuit) to the case then it is an isolated (2 field wire) alternator.
So many more tested to locate the issue
