Actually the answer is a most definite yes. I happen to have a 12 volt 56 here and it is more trouble than it is worth. If it actually ends up being mine, it will be turned back to a 6 volt magneto equipped Cub because that is the way it originally came.
For the most part, Ellie, never fails to start when I need her unless I need to do some more maintenance. On a 65 year old tractor there is always maintenance to do and living close to the ocean there is always corrosion to deal with as there is a lot of moisture in the air and it doesn't matter if it is 6v or 12v. As I said before repairing a 6v generator, getting a good 6v regulator is no more expensive than buying an alternator as well as a new 12 volt battery and all the bulbs and upgrading the ammeter if needed. That gets expensive. Read this thread again ... - Generator and Cut-Out
. I got my genny's done, a s/g and a new regulator for around $300.00 and that is cheap up here. It was also done at a qualified genuine AC Delco Service Center using Delco parts. Definite class job by class techs. And they can usually do a generator in an hour. That is cheap especially to have an original redone properly. My local shop has lots of 6v generators for Cubs which surprised the heck out of me and they are very reasonable. One just has to be imaginative and not want everything right this second. A little patience goes a long way.
So yes, I do believe that a well maintained 6v system is the equal of any 12v system. Remember - I live where temps below -50 are not uncommon. There are days when my vans won't start and they are all 12v, but Ellie will ...
Yes she is kept indoors and on a Battery Minder but that is only part of the story. Well maintained is the key.
Is there a place for 12v. Most definitely. Like 6v it is not the only answer. It depends on a lot of things. If your Cub was missing the genny, cutout and battery, then it would probably make a whole lot of sense to convert it over properly
to a 12v system. However, if you still have all the original equipment and it just needs maintenance then it is far more economical to fix what ever the problems are with the genny and cutout/regulator as well as any other underlying problems than to convert it over to 12 volt and still have the underlying problems. Also, if your Cub came with 12 volt
, then by all means leave it exactly that way - just make sure the maintenance is done.
I guess it is like Oil, Paint, Hydraulic Fluid or tire brands - it all boils down to personal preference, personal budget restraints and of course the desired outcomes - restored to original, repaired to be a working tractor or somewhere in between.
