New ignition trouble, MAYBE
I too am running a MP regulator. It's been on there a while, so I'm not sure why it would suddenly die (then again, regulators don't gradually die, do they? :D )
On Moparchat someone mentioned checking the field wires to ground, said if they are grounded, it would tell the alternator to produce whatever it could at a given RPM.
I did some electrical work on the car, but only repair of individual wires, and removal of the effeciency circuit. I can't imagine where I grounded a field wire. I am going to look into it, non the less.
I REALLY need to break down and get the factory service manuals. The schematics in Hanes & Chiltons suck.
