Got me an old D17 and was reading on hear about them being postive ground systems, how do you know if it still is this way or can you even change it? My battery was hooked up negative ground like a normal one and it starts ok so far, just want to make sure previous owner wasn't messing it up!! Thanks!!
 
Dose it have a generator or altenator on it? If it has an altenator it has been changed over. If it starts and runs and the battery stays up dont mess with it. If it aint broke dont fix it. Bandit
 
originally the tractors battery was charged by a generator. It had a black box for a voltage regulator, under the gas tank. A generator looks like a steel case motor at the front right side of the tractor. It puts out DC current. It has a belt drive. It is about 5 inches diameter and 9 inches long and normally black. Will have two wires to it, marked "A" and "F" on the case of the gen. THe wires set on the studs with nuts to hold them down.. An alternator is a different kind of charging system. It uses alternating current with a rectifier and internal voltage regulator. Most alternators are aluminum case and about 6 inches diameter and 6 inches long. The wires will probably be two in a two prong connector on the side of the alternator back edge, There will be one big wire on the back that is connected to a threaded lug stud.
 
this little tractor has an alternator, the alumimum unit behind the radiator, belt drive

You can't be too sure about what generator it has on it either..
If it is 12V, it could have been changed to - Ground with an automobile generator installed..
Best way would be the Amp-meter..if it shows a "Charge" when running, the battery is installed properly..

You see how big the alternator is in Steve's pic? A generator won't have any aluminum in it and will be about the same diameter as the air cleaner in his pic.
