FORD Myth #3: A 12V System is an 'upgrade'. FALSE.Fellas just fail to understand the 6V system and subscribe to all teh myths and fallacies they hear.
The last iteration of the OEM 6V charging system (8N-10000B/10001) in perfect shape produces 6V x 20A = 120W of poorly regulated power. That is barely enough to run two dim 30W headlights, a 30W worklight, a tail light, and the ignition system. The versions used prior to that produced a paltry 75W of output and were not capable of sustained operation with lights.
A 12V 10SI conversion produces 12V x 63A = 756W of perfectly regulated power. That is enough to run 3 or more 60W lights, tail lights, flashers, ignition, a 12V sprayer, and a modern radio while keeping the battery in top charge. It will crank faster and longer than the OEM system and does not require constant tinkering to keep the connections sparkling bright and the system operational.
Your opinion not withstanding, the vast majority of people consider those improvements a MAJOR upgrade.
