Hadley, great question here's the deal.
First of all, regardless if the condenser (aka Capacitor) is used in a 6 or 12 volt system, that's (6 or 12 volt system relative to the condensors insulation properties) in the scheme of things NOT MUCH DIFFERENCE. The voltage withstand rating, or the insulation value if you will of the condensor, IS MUCH HIGHER THEN 6 OR EVEN 12 VOLTS anyway and may be the same if used on a 6 OR 12 volt system. The critical factor is the capacitance which, if properly matched to the inductance of the coil, increases the life of the points and reduces the situation where there's mounding on one set of the points and deep pitting on the opposite side, one among other SIGNS OF AN IMPROPER SIZED CONDENSOR.
If the condenser is undersized or not even there at all, the coil can still produce a spark, but the points will burn prematurely.
Some time back I spoke with a rebuilder who claimed nearly 50% of the condensors he buys in bulk are out of spec grrrrrrrrrrrrrr
SUMMARY there's not much if any difference in the voltage withstand or insulation value of a condenser regardless if used on a 6 or 12 volt tractor HOWEVER there's a HUGE difference if its not sized correctly to match the coils inductance.

Today's Featured Article - Sunday Drives - by Cowboy. Summer was finally upon us here in Northern Maine. We have two types of industry up here, one being "Forestry" (Wood Products) and the other "Farming" (Potatoes). There is no shortage of farm tractors and equipment around here! I have been restoring old Farm Tractors for the past 6 years, and have found it easier and less expensive to hit all the auctions and purchase whole tractors for parts needed.
