Re: [Chrysler300] 1960 "F" Generator

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 ...

The generator/alternator shop says the armature on my F's generator is shot - shorted out. Unrepairable. Do any of you have a source for a generator, or a generator for sale?

Second question: the shop says F's manufactured late in the prouction year had alternators installed. I've never heard that - any truth to it?

Viscous fans only limit how fast the fan spins in relation to engine RPM...... There are Thermostatically controlled viscous fans which also "lock up" or "tighten up" the drive of the fan related to temp. If the fan clutch has a spring in the center of it, its a thermostatically controlled fan. If not, its only a viscous fan. If a fan clutch goes bad, typically it will appear to be real loose, and may even appear to not spin in relation to the engine, if at all, at idle.. If the fan "freewheels" and has very little if any resistance (engine off of course)...... the clutch is probably bad.

Do I understand correctly that once the engine is hot the fan should become more difficult to spin as the fluid inside the clutch becomes more viscous? Seems like mine stays rather easy to spin when stone cold or after running for some time. Asking because the car seems to run warmer than it used to (not hot, just warmer).
