Charging system voltage high

Well after checking stuff for most of day today I am still no closer to problem. I checked all bulkhead connectors and the are good. While bulkhead connectors were apart I unhooked everything that the blue wire that goes from alt to voltage regulator goes to and performed a voltage drop test on that circuit and it had no voltage loss and it lit a halogen light good at all ends,so I think that wiring is good. I checked voltage loss across ignition swicth with car running and it has battery voltage going in on pink wire and only loses about .2v coming out on blue wire. Voltages with car running are 15.2-15.4 at battery and battery end on back of alternator,14.2 at blue wire at ballast resistor,voltage regulator,and alternator field. Blue wire that goes from ignition switch to underhood loses about 1v between ignition switch and components but that wire feeds ballast resistor,control module,goes to voltage regulator and alternator. I also charged battery for a hour to see if that would change anything and it did not. Last thing I did was put a jumper wire between battery in and battery out of ignition switch and that also did not change anything.
