YEP- back out wires on the connector - easy fix, hard to find. Alternator was same deal, the 12v signal from ign switch had loose contacts, swapped out for a new ign switch and connector. She purs like a kitten at 13V, good enough with a 10rib SC belt and UD crank pulley.
PS thanks for the carfax, glad to confirm accident free after 140k miles. WOO HOO
