I like the idea of having a key for my 440 because some times i need to leave it on a job.my show crawlers i leave the negative cable loose and remove it from the battery at the shows just in case?

Thanks guys!!!
i have decided to go the 12 volt route, and have my starter and generator being rewound for 12v instead of 6v. getting everything done for $105.00 at a local rebuild shop, i dont think that sounds to bad? and that price also includes a new regulator and coil!!!
i am also going to install a key type starter switch and a solenoid switch just for safety!! all i need now is new steering clutches and a little bit more fresh paint and i will have the old girl back in the woods!!!

Hi: I'm curious, why would a person want/need to convert to a 12v system? Are there any particular advantages? Thanks. Paul

12 volt the engine will wind over faster, more products available for 12 volt, smaller batteries, less current required to start, wires dont need to be as heavy. These are some of the popular reasons. The alternator tends to be a little more robust than the generator. But its really a matter of prefference.

My tractor was 12 volt, yet a properly set up tractor on 6 volt, all the abve reasons are moot point.

Thanks the info you shared is helpful. So far mine's working well as designed (6v), so I'm not looking to convert. Paul

By and large a 12 volt conversion is only to hide an existing charging or starting system problem that if fixed correctly would work just fine on 6 volts.
Converting the starter and generator to 12 volts is the best way to do it by far. It eliminates the starter drive, housing and ring gear damage issues associated with 12 volts on a 6 volt system.

Paul, my primary reason for making the switch is lighting, my original gen needed to be rebuilt and it just made sense to make the switch now. i plan on running lots of lights for night work around my cabin, and the sheer cost and availability of the lights made me make the switch. i am keeping the original looks by using the 6v housing and now if i need to jump start the ole girl i can use my truck.
