See if this article sheds some light. "Typically, the feed side of the ballast has two wires-a brown ignition start wire and a dark blue ignition run wire." http://www.moparmusclemagazine.com/techarticles/engine/mopp_0301_mopar_electronic_ignition_system/photo_23.html Thanks, Gary H. -----Original Message----- > > >This is on a 64 Fury 383 with cobbled up under hood wireing. > >issue #1-points distributor-wireing to the input side of ballast resister. >We know that when engaging the starter, voltage to all systems is reduced. >However there is a wire that maintains full voltage even when the starter is >cranking .
