heres the rundown.
the battery is less than a year old and was charged overnight with 6 amp charger,yes i realize charge is now down 12.4 as noted.
initially battery with car not running was 12.6. after starting car 14.7 at idle at battery and alternator bat stud- increasing rpm it went over 15.
checking anywere in the charging circuit from bulkhead to ballast to volt regulator to alt field terminals showed a loss of 1 to 1.5 volts between the battery and test points with key on and not running.
bypassing/disconnecting the blue wires and running from the battery only to alt and volt. reg i now only lose about .1 of a volt at the test points(various gauge scrap wires just temporary alligator clipped at connections) and running idle voltage is around 13.6 and climbs to 14.2 with rpm increase.
so i will charge the battery run new wires and as advised power the circuit off a relay and hopefully end up with low 13 ish volts at idle and 14.5 or so max.
