The 6600 should have a Motorolla alternator...
The exide batteries in those tractors are noted for giving 5 years or less service, particulairly if they've been run down, or overcharged due to a poor charging system.
First thing to check is if the tractor is charging. Does the indicator light light up when you turn the key on? Does it go out after the tractor is started and revved up a bit? If yes to both, then it's probably charging OK. If the light doesn't light when the key is turned on, then th ebulb is probably burnt out, and should be replaced. If you have a Multimeter, or a volt meter, check the battery voltage with the tractor running. It should be over 14 V. Beyond that, check all the battery connections, and the general battery condition. If the battery top is encrusted with a whitish layer of crap, then the battery has likely been overcharged. If it is like this, get some warm water and baking soda and clean the battery. This layer of crap will conduct current to ground and discharge the battery. The battery should also be load tested. You'll likely have to take it to an auto parts store or NH dealer, or some other garage to do this, or else check the battery for dead cells with a battery hydrometer. Giving the battery a good charge while disconnected from the tractor, and then load testing, or simply using it to see how it performs will give a better idea of it's condition. Chances are that if it still discharges while it's disconnected, then it's bad. If it only discharges while connected to the tractor, then something is draining it.

The easiest way to find a current draw on a tractor is with an OHM meter. Disconnect the wires at the starter, and with the ohm meter, check each wire for resistance. When you find a wire with resistance, follow it, and find the fault. With the key turned off, nothing should be drawing current or showing resistance. That's the idea anyway. If you need more info, post back.
