Positive ground in automobiles was mostly abandoned with the introduction of 12-volt electrical systems in the fifties. 1955 was pretty much the last use of 6-volt electrics in American-made cars. Most cars switched from 6 volt positive ground to 12 volt negative ground together. One exception to this was the 1955 Packard, switching from 6v to. My 48 Dodge D-24 [ by the previous owner ] was converted to a 12 volt system, however, it was kept as a POSITIVE ground system. It has a 12V generator that is working fine. I am switching it to a NEGATIVE ground system tomorrow. Anything I am missing in the following steps: 1. Disconnect the battery Transition to negative ground came with the change to 12 volt systems and the use solid state components such as alternator rectifiers, transistor auto radios, etc. Apparently these early devices were cheaper to manufacture for negative ground. Thus negative ground became the 12 volt ground standard and has been retained ever since I restore old tractors that were originally positive ground 6 volt, i think that is a better system than 12 v neg ground for these reasons. I lived where 40 below 0 was common and these tractors never failed to start unless there was a problem and since it has been mentioned about corrosion the units i see corroded the worst are the ones. A positive ground system works by directly connecting the chassis of a vehicle to the positive side of the vehicle's battery. This system effectively earths the vehicle as the chassis attaches to the battery using a positive battery cable. The cable is tethered to the battery at one end and the engine block at the other.
