Then you're half way home. Pull the plug from the voltage regulator and jumper from the FIELD tang over to the POWER tang (first and third holes on the plug from left to right) and make sure you have 12v there when the ignition is on. Start the engine and gently rev it no higher than 1500 RPM or so. If you have a nice 14v, then the problem is the voltage regulator, if the voltage does not rise, then the alternator is bad or the connections over to it are bad.
