There is a question of how fast it drains the battery. If it gets things hot, and the battery is pushing out 100 amps or so into a short, it needs to have every heavy (battery cable) checked for shorts to ground. If these are good (and "0" ga wire) then the starter switch could be grounding internally. If the switch and wires are good, then it probably is not shorting to ground, but may have the following wrong:
If the voltage regulator contacts are sticking (on the cutout relay in the regulator, the generator will continue to draw current when the tractor is shut ovv (as much as 15 amps) which will kill the battery in a few hours or so. If the amp meter is connected correctly and working, this will show as a discharge even when shut off.
I suspect this is ths case because the first problem (above is usually including smoke.
A new regulator will probably fix the problem. If not check the archives for John T trouble shooting guide, it is sxcellent. Good luck, JimN
