Re: [Chrysler300] 300 G Alternator

They are all the same , nothing critical about the numbers or engineering . It eliminates RF interference , but can do little about alternator “Whine” . Not what it is for . Alternator output is 30 A or more takes a huge capacitor to filter 30 A at 12v . Like 1 farad . About 3” diameter and 8” long . Sold for custom stereo . The problem you are hearing is most likely bad capacitors in the radio which filter the 1 amp or so the radio uses . Take to radio guy or ham radio guy , replace filter capacitors , typically 1000 uF 25 v . Leave old one add new ones ( modern much smaller , Panasonic is best one) . Trying to get old big can out of board can destroy old printed circuit  board .  
Hope this works out for you .

                 I was attempting to replace the capacitor with NOS part number 2421137 and noticed it is very different than what is on the car. The new one has a threaded shaft while mine is like the one shown in the FSM 61 Supplement. The alternator case has numbers embossed as follows: Assembly 2095100 & Alternator 2095300. Is this correct ? My purpose is to eliminate some radio noise while the engine is running. Appreciate any thoughts.
