Generators can be DC (dynamos) or AC (alternators). Alternators can give current output up to 35 amps whereas dynamo output is limited to 12-14 amps. Regulator is also fitted on the tractor to regulate the current produced by the generator.
The alternator acts like a pump to top the battery up and supply power to the rest of the vehicle. Usually attached to the side or top of the engine and driven via a belt, the alternator chiefly consists of two windings of wire.

Make sure your alternator’s positive and negative terminals are clean.
Put the multimeter’s black cable to the negative terminal and the red cable to the positive terminal.
Look for an ideal alternator reading of around 12.6.

What’s the difference between an alternator and a generator on a tractor?
An alternator is a device that converts mechanical energy into AC electrical energy.A generator is a mechanical device which converts mechanical energy to either AC or DC electrical energy. An alternator always induces an alternating current. A generator can generate either alternating or direct current.
Does a tractor have an alternator?
Most lawn tractors possess one of two types of charging systems to help keep the battery up and running. One type of charging system is the belt-driven alternator, typically mounted on the engine. As the belt turns the alternator, the alternator continually generates power to recharge the battery.
Do farm tractors have alternators?
Tractors require alternators that can handle extreme weather and frequent usage. That’s why we manufacture our alternators to be heavy duty for long-term reliability. We realize the importance of the job that farmers do, and we sell tractor alternators that operate to the high standards required to get the job done.
What voltage do tractors use?
Most typical farm or road vehicles use a 12V system; larger commercial vehicles may use 24V electrical set-up.
Why does my John Deere battery keep dying?
Your lawn mower battery could be draining from a number of causes such as loose, dirty, or corroded battery cables, electronic drain, or a bad battery. There could also be a faulty charging system, a failing voltage regulator, or other issues that are draining your lawn mower battery.

You can jump-start a riding mower with a car. Most mowers operate a 12-volt system. Put the jumpers on in sequences 1, 2, 3, 4, and start your mower. With the mower running, remove the jumpers in reverse order 4, 3, 2, and 1.
How do you know if a 12-volt battery is good?
How do I know if its the battery or the alternator?
Jumpstart your car. If you can turn the engine on, but it dies shortly thereafter, your car alternator likely isn’t able to charge the battery. On the other hand, if you jumpstart the car and later on it fails to start on its own, it’s likely a dead battery.
