Hi Mike, Pretty much all 12 v non ac generators and VR are the same 30A in mopar 57-60 —should find one readily - used on line / eBay . Sometimes nos armatures too . Sometimes “clocking “ of front or back plate is different . Can use your parts .
Armature is very reliable in general just brushes go . Change those . Poor brushes, stuck brush springs ( common) can roughen copper bars on armature . AC generator and VR are rare , more amperes , possibly several versions ,35 and 40 A . If ever no charge after sitting , first tap rear of generator with a hammer . Away you go Some external event had burned it ? Messing with VR or “ jumpers “ are most likely cause . VR had a built in current limiter , gen armature therefore cannot burn out in car in use . If you push down on the reverse current relay in Vr (the golden finger) with engine off it will lock in and burn up armature with key off, after you walk away . Have seen that many times, sadly . Battery current then flows backwards into stopped generator till battery dies. Burns armature winding up . You Can cause same thing messing with jumpers . And jumpers can blow up VR . Do not open VR can, thinking you can adjust etc . All you can do is cause harm , unless you really understand it and even then there is absolutely no reason to think the correct and critical factory adjustments have changed . Run from anyone who says it needs adjustment. If defective get a new one . (2 resistors in back of it rust at their clamped ends sometimes, lose connection ) To close that out, it is not just contact gap and spring tension that matter it is the air gap to the pole pieces too . All interact . Bending anything destroys all that . None of the above — even told to smart people — prevents the golden screwdriver of the left side of bell curve from burning generator and wrecking the precision of the Vr, sadly . Think of it as a sealed watch. Cover should have been riveted on . 4 speed F had alternator , prototype , I think . Due to special headers. . But not used in production to my knowledge . G parts would fit ,— I believe exhaust manifold changes F to G . G alternator exhaust manifold therefore a rare bird? F is rare , would keep all stock ... j Sent from my iPhone not by choice On 31 Aug 2019, at 6:54 am, Michael Reed rmreed@xxxxxxxxx [Chrysler300] <Chrysler300-noreply@xxxxxxxxxxxxxxx> wrote:
