I've never voiced my opinion on the 6 vs 12 volt thing, but, today, I'm a gonna. To me, it's just like the water in the oil thing. They don't get used enough to drive the water out. Same way with the electrical system. This system was designed to be used hard and long and it worked. But, you say, I use mine every day. Lets tear that apart; Say you got your little wagon behind the tractor and you're planting your white pine trees. You dig a hole and put the tree in it and fill in around it. Then you start your tractor and pull up ten feet and do it all over again. You have 35 trees to plant. You work till dark and then (because you can) you turn the lights on (cool) and head for the barn. After a period of time using your tractor like this, you start having problems. It won't start, the battery died. Damned old 6 volt system, that battery wasn't even two years old. Why did this happen? Get out your FO-4 and follow along. It says that each hot start requires 100 to 150 amps. The electrified guys, (Dell and Claus) tell us that the coil requires about 3 amps to keep the engine running. If I'm not mistaken, each light requires 5 amps. All this from a generator that in new condition puts out about 11.5 amps and it does this at around 1000 to 1500 rpm, not at slightly above idle. (shes an old tractor, I'm gonna take real good care of her and not run her hard) Well, are you starting to see where I'm coming from? You ruined the battery by shutting it off in the down condition and it started it's process called sulfiding (deterioration). How do we get around this demon? We start by buying our new 6 volt battery made specifically for a tractor. (Yes, there is a difference, they are built heavier than a car battery.) Then, use the tractor in your usual manner and when you pull it into the barn-hook up a trickle charger to it and all will be well. The reason you don't hear the fellows with 12 volt alternator systems complaining about this is; An alternator can put out 40, 50, even 60 amps and it can even charge some at an idle, (not so with a generator.) So, it boils down to this-if you use your tractor lightly, help out it's electrical system by putting the charger on it when you are done with it. ( we already know to keep everything bright and shiny and tight and to keep the water level above the plates in the battery.) Or, go to the alternator system and eliminate it. The choice is yours, it's 6 of one and 12 of the other. L8R----Fred OH
