I'm going to get a Cub running that hasn't run yet this season. There is no battery in it and the guy that used to work on the tractor isn't round any more. How can I tell if its a 6 volt or 12 volt system. I believe the tractor is 50's vintage as its red and has a 1 pt hitch.It has a mag that has been converted to an external coil.I'm assuming from the factory it was 6 volt but don't know if someone could have changed it.

You can probably look up the tag number on the generator and determine if that item is 6 or 12 V. Presence of a ballast resister ahead of the coil would likely indicate 12 V But absence of it not necessarily. Most coils or voltage regulators are not marked once you take them out of the box. If you hook a 12 volt battery to it and the lights come on real bright and then go out you can bet they were 6 V bulbs. Good luck

it is 6 volt, and 12 volt dont even make sense for a conversion as that tiny little engine spins like crazy with 6 volt anyhow. with a mag 12 volt is definitly not nesessary as you are defeting the mags purpose. any tractor or engine with a mag does not need to be spun fast to start. just keep everything tuned up and no problems.
on the other hand you never know what the poor thing has gone through.

it does make sense to convert them they get 75 to 80 bucks for a 6 volt and 45 to 50 for a 12 volt sorry but I am going to take the more bang for my buck and for almost half the money
I agree with you but who knows what someone has done in the past. Seems like every time someone has trouble cranking with 6 volts the answer is to switch to 12 instead of fixing the problem. My A is 6 volts and it cranks it like crazy. Can't imagine what 12 V would do on a Cub.
Not to mention the modern world using only the 12 volt system. If on six volt you must have special battery chargers and you lose the ability to jump start your tractor. That right there is enough to make me think about converting everything I own if one of the electrical components goes bad.
Depends on how old the Cub is. From about 1964-1975, they would have a 12V generator on them.
You need to be a little more sure about the age of the tractor other than it "looks like it's from the 50's." There is a serial tag on the lower right front of the tractor where the steering wheel shaft enters the steering gearbox. Get that number and post it.

I havent been able to buy a 6 volt where I am at for 45 at least for the last 3 to 5 years I am in south new jersey
I doubt you have Farm & Fleet, but are their choices. I haven't put a new battery in a tractor for 3+ years. They get my hand me down truck batteries or I go to the junkyard and get a "good" (per a load test) battery for $15-25. I would like to see you do that with a 6 volt.

If the Delco-Remy tags on the starter & generator are still visible (usually painted over) a black back ground denotes 6 volt, a red background denotes 12 volt, that is, if they are original vintage. If you can post a pic of either or both tags, or give us the number on the tag we can help you determine which voltage it actually is.
