[Milsurplus] Acc Bus

Brad,

No.  Most had no keyed ignition or starter switches either.  Radio power went 
directly from the battery (or post on starter relay or solenoid) to the radio 
power junction box.  Radios were often operated with engine off (in ground 
vehicles, not aircraft we hope).  Same with the M Series.  Later M Series 
(Vietnam War on) have MX-7778/GRC Transient Suppressor Assembly added because 
drivers often disregarded posted warnings to turn off (solid state) radios before 
starting engine.  I'm not sure what the current in-service vehicles have, but 
would be surprised if it has changed.
