In addition, until December 1943, Jeeps were outfitted with a series of capacitors and straps attached at precise points to absorb and damper interference to radio waves known as Radio Suppression.
While researching for my rebuild, a common question was asked- was I going to restore the jeep as 12 Volt, or keep it at 6 Volt?
This is a highly contested question as there are parties in the Jeep community who feel that 6V systems are unreliable and outdated, and its easier to get new 12v parts. While on the other hand 6V is the more authentic, and only, 'correct' answer.
As my goal with this rebuild was to be as authentic as possible, I elected to go with a 6V system.
As opposed to modern automotive electrical systems that utilize an alternator to maintain battery charge, vehicles from the 40's used a generator and a voltage regulator to maintain this charge.
In addition, a system of electrical shielding was implemented to suppress radio interference generated by electrical systems. During the war, there were two different methods implemented to suppress radio noise.
Type I Radio Suppression was used throughout production until December of 1943 (MB serial # 289001) and consisted of several capacitors and bond straps.
