6V vs 12V problems tally sheet

I've never heard the claim that a 6V system was "better", rather the purists saying that it was good enough and didn't need replacing. I grew up in Southern Tier NY, and was well-versed in this stuff since a little kid. Gramps had the local IH dealership (Cohocton Valley Garage), lime spreaders, dump and farm trucks and a farm fleet. '51 and '53 REOs and '52-'53 deuce n a halfs with REO engines, and lots of other 6V deals. The 8N with a Wagner loader had to start to plow snow and load coal and got an 8V battery and adjustable regulator, as did the '53 Chebbie ton truck that delivered the coal. Despite the incoming cries of derision, both started very well, sometimes after being dug out of a fresh snowdrift, and the lights on the Chebbie were bright like a 12V but needed no modifications. Both ran for years with zero problems. All 3 of the 6x6's got converted to 12V from the military 24V systems. One of gramps' favorite tricks was running a 6V starter on the REOs that were 12V systems, again worked very well with zero problems. On my converted 8N and 850, I removed and kept all the 12V charging systems and stashed them away in case I ever sell them to someone who just HAS to change them back to roww-roww-roww
 
12V one wire alternator conversions are for the cheap , lazy and electrically illiterate.

I agree on a car/hot rod. But on a tractor you really don't pull many amps. All you are running is a coil and maybe some lights. 1-wire works OK if you are nowhere near the capacity of the alternator (like the typical 37A). 10si is easy-and better-to wire as 3-wire. But in the last 10 years going to tractor shows I doubt I have seen more than 10 tractors that were 6V still. 95% of the rest had Delco 10si alternators while the other 5% had Delco CS130 (why!?!?), Ford 3G external regulator and a few Hitachi and Ford 4G.

Again, just for the record there is nothing wrong with 6V. If it works for you, then great. I just laugh at "12V devalues by $1000". It's pretty easy to reverse the change if you are so inclined. It's not like you have to cut a hole or weld on anything anywhere. I had a 6V Generator, regulator, and harness from a late 8N for sale. I had no interest in it. I still have it.
