How many volts should a stator produce?
For each 1000-rpm, a 32-amp stator should have 18 volts AC (VAC) per it. It should be 36 VAC by 2000. 54 VAC is what it should be at 3000 RPM.
How do I know if my stator is bad on my lawn mower?
You can check the ohms on the stator by checking while not running. If you put the red lead on a terminal and ground you should get a reading of about 1.5. f it reads nothing your stator is faulty. Your AC voltage while running should show 28 Volts or more.
How do you test stator output?
Insert each probe into a stator socket. You should read around 0.2 to 0.5 ohms. If you show an open circuit with the “Open” or infinity reading or have higher resistance, then the stator is bad and you must replace it. If these tests all produce positive results, then the stator itself is good.
How many volts should a lawn mower voltage regulator put out?
The voltage should now rise to about 13.8 – 14.5 volts. Here is what it means if you get anything lower/higher: Where the reading is less than 13.8 volts, your battery is slowly losing charge and you’re supposed to recharge it. If it climbs above 14.5 volts, then your regulator is already damaged or will soon go bad.
What causes a lawn mower stator to go bad?
Often what causes this is heat or overworking the stator. Trying to charge a battery that is bad will cause the stator to work much much harder producing amperage that the battery will take, the end result is once the amperage gets high enough the coating melts off the coils causing a short..
How do you check voltage on a lawn mower battery?
Lift the seat on your riding lawn mower to access the battery. Turn on the digital multimeter and switch it to “DC” or “A” to test battery voltage. Set the meter to a value of 13 V for a 12-V battery, which is one value higher than the expected reading.
How do I know if my stator or rectifier is bad?
Key Signs to Look For
You won’t have any trouble diagnosing the faulty regulator rectifier if the battery is the cause. You’ll note signs right away like poor starts, fluctuating meter readings, and dimmed headlights. around 13 volts, the bike will start to drain the battery.
