M Farmall Points/Condenser need changing from 6-12V?

I know when you ask for points and condenser at the auto parts store they don't ask whether its a 6 or 12v so I'm assuming they work for either voltage. But, just to be sure I'm checking with you guys.

Got the M going today after replacing pistons/rings and pretty much going through everything related. I'm pretty sick of the old thing after two weeks of part time wrenching on the freezing ground in N MN.

Lots of details left but it sounds very good. Used the old head gasket so a retorque hopefully will cure some tiny bubbles i see in a couple spots on the block.

But my respect for the guys who designed these tractors is always high. I have a 39 B that I use regularly for mowing, grading, towing a wagon....it just couldn't be better. (yes they did make Bs in 39)
 
the points and condenser are not volt specific. but if i were you i'd be getting electronic ignition and a good coil. it sure makes them start and run good. and a extra plus is no more condenser.
 
Dave, they dont ask cuz it dont matter. The points act more as a CURRENT switching device and its how many amps (around 3 to 4) they need to constantly switch on and off that matters. Also, the DC voltage withstand rating (which is what matters) is wayyyyyyyyyyyyy higher then 6 or 12 volts anyway so the insulation and distances between parts of different voltages (part of what determines how many volts it can withstand before arcing over) being soooooooo muchhhhhh higher then 6 or 12 volts anyway dont matter if youre using it on a 6 or 12 volt system...

Nowwwwwwww if the condesnor werent there
then the points would burn up like reallllly really quick lol
