[Chrysler300] Re: Ground polarity





My first car was a 1958 DeSoto. So I guess I missed
All that. My dad never said
Anything about + ground.

Most 6 v , not just Chrysler were  + ground . Plus or - had no real advantage at first .  So probably 55 300. Was + ground ( 6v) 

12 v tubes ( that will run without vibrators to step up volts  )  came on scene contemporary with 12v cars ; radio design with those new tubes ( about 54) required generally that anodes of tubes are + , so the normally grounded tube cathodes are -. There was a real reason to go - ground then. 
However transistors used in output were temperature  fussy PNP germanium , and required the opposite , why the mica washers and sort of inverted design of output stage of those hybrid radios common in our 12v  cars  . Later NPN  silicon transistors run the same  polarity as tubes, all is happy .
If you do jump a car backwards generally your radio is   toast       , transistors will blow and Electrolytic capacitors  fry . Before fuse blows..

As a teen working in a full-service station in the ‘50’s, I quickly learned that MoPar meant positive ground and LH threads on the driver’s side.  Nothing like a tongue lashing by the experienced mechanic as I tried to change a tire on the driver’s side of a Chrysler or the big flash when the jumper cables were attached incorrectly.  I’m sure there were competing theories that differentiated the products of the big three but I recall an early belief that the problem was more organizational stubbornness than technical veracity.  Still a lot of that going around as we remain very human.

Smoky and hot Brentwood, CA—but can’t complain as many have it worse.  Human, livestock, pet and wildlife lives continue to be lost as well as massive property damage in the CA fires.  I did see a picture of a burnt-up ’39 Ford in the news and assume other collector cars were lost.  Hoping the insurance companies treat their customers fairly.  Hot temperatures and high winds predicted for today.
