I have a 1969 barracuda with a 318 single wire alternator. I'm only getting 12.2v out of the alternator I have went through the wiring and replaced the alternator and regulator and I got no change. Does anybody have any suggestions?
 
first is there 12 volts to the main pole on the alternator then check for voltage at the to plug on wires when ignition is turned on
 
Yes I'm getting 12 volts at the post and all the wiring is good as far as the wiring diagram goes
 
Are you getting 12.2 from the back of the alt when the car is running or from the battery?

You said you replaced the voltage regulator did you make sure that it has a good ground connection?

The bulkhead connectors are also suspect, especially behind the dash where you can't see them.

What does you amp gauge say? does it even work?

Also and i hate to even ask but you did double check all of the connections you have loosened removing both correct?
 
You probably have the typical voltage drop between the battery and the voltage regulator. There's lots of blogs on this subject.
