Kohler Small engine battery keeps draining
If your Kohler small engine battery keeps draining, the charging system is not replenishing the battery while the engine runs. The most likely cause is a defective voltage regulator. This part controls the voltage sent from the alternator to the battery, and when it fails, the battery may not receive enough voltage and will drain quickly. A faulty alternator is the next likely cause. Test the alternator output with a multimeter to determine whether it is producing the proper voltage. These failures can cause several related symptoms, including a small engine battery not charging, an engine that will not hold a charge, or an engine not charging the battery during operation. Before replacing a part, inspect the battery connections and wiring for corrosion, looseness, or damage, and confirm that the battery itself can hold a charge. Enter your Kohler small engine model number to find the exact replacement voltage regulator, alternator, or other charging-system part for your specific engine. Using the correct model information helps ensure the replacement fits and works properly.
01 - Kohler Voltage Regulator
While the engine is running, the voltage regulator sends the proper amount of voltage from the alternator to the battery to keep the battery charged. If the voltage regulator is defective, the battery won't receive enough voltage, causing the battery to drain quickly.
