How can I tell if a tractor’s alternator is dead?

The most common signs are a charge warning light that stays on with the engine running, a battery that discharges within a few days, or voltage that does not rise above the resting battery level. First, check the belt, ground cable, and connections. If the problem persists, the alternator or its voltage regulator is likely at fault.
