Stll pushed 30+ volts. I then went and had Gen2 rebuilt at a different vendor... (cost $25.00 helping out an ole school disabled vet... PRICELESS.. He has a customer for life BTW....) Went ahead and paid him to build me a replacement spare, should be ready in a few days.... System currently still pushing 29-30 volts... Thinking the high dollar rebuild on GEN1 is kinda hot, cranking out a full 15+ volts... ( voltmeter in dash currently sits just a hair in the red, and not in the normal green position..) gonna wait until i have spare in hand and installed to see if it drops it down to the correct 28 volts.
Suggestion:
Check the voltage across the terminals in each battery separately with engine running and dash voltmeter in the red. Report back what you find please.
Sorry for the delay... its been about 3 weeks since i could get back to this... Was finally able to pick up a 3rd ( spare ) alt i had built... swapped it out this past weekend.. and Cha ching... its charging correctly again.. at 28volts.. All is good now with ole Beulah.. took the Alt in question and had it tested... and its a HOT one.. putting out 15.8 volts.... So, its still under warranty... gonna get those idiots in Nashville to fix it..( this will be the 3rd and last time, i have them do any Alt work for me...).
So, now... with a new job change, and some medical stuff coming up... gonna have to hold off on any new upgrades for a bit...
