(49122 mi) Gee whiz! The car body is part of the Circuit!

   Way back in November 2012, I decided to tackle the immense job of re-wiring the Chrysler.  All the original cloth-covered wiring was disintegrating with the renewed usage, and the Los Angeles ozone probably didn't help either.  In any case, the wacky gas gauge convinced me that a re-wire was absolutely necessary to improve battery and sensory behavior.  I learned many new things about electrical systems on a car - the biggest revelation being the frame/boy is part of the circuit.  If any wire was exposed to the body without insulation, that wire was short-circuiting the system, and all hell could break loose.  

  The biggest problem was ensuring that only desired grounding occurred.  Surprisingly, grounding some parts of the car was harder than it should have been.   The positive cable off the battery leads to the engine block, which means that the car is a positive-ground system.  The 6-volt system also makes it a bit more twitchy than 12 volt cars, or so I've been told.   

   The illustration below shows the original schematic adjusted through Photoshop, and I included changes to the colour of the wire and its gauge.  Frequently, the gauge of the wire as appearing in the original manual was different than the wire gauge in the car.  I updated the information for my own purposes.
