I would agree about the regulator unless it has an internal regulator. If so, it would still need a seperate connection for the load or it will nearly free-wheel all the time and the battery will receive only minimal or no charge. With an internal regulator, some alternators will need a wire connected to a 12 volt source such as the idiot-light on a auto (you would need to determine the model of Alternator and find a schematic for the wiring of the vehicle that model is used on) though not direct to the battery (this causes full charge all the time in the same manner the other post described). You would know if it is not fully charging by low indication of charging after starting, ie after a drain, the charge should jump up for a short time then settle back. Could this have anything to do with your starting problem? A low battery could contribute. To guess further, if there are significant variances in the compression of the cylinders, there may be a tendency for the engine to stop at the compression stroke of the strong cylinder. If the battery, starter or wires are in poor charge/condition, spinning beyond this will allow a lower amperage draw at that first moment the starter and battery are kicked in, if this were coupled with a magneto impulse coupler (since the low battery would contribute to weak start on a battery ignition), the engine would still kick and run just fine especially with a very slow RPM turnover. This is all very far fetched since I am guessing too much. Post more details about the starting problem, which model AC it is, mag or battery ignition, and look around for an regulator case. Chris : I can't imagine it not having a regulator to control direction and amount of charging current. I would expect someone has rigged your tractor otherwise. See if you can get a shop manual and check it out. You could blow up a battery and could also burn up your electrical system.
