Husqvarna Small engine battery keeps draining
When your Husqvarna small engine battery keeps draining, the voltage regulator is the most likely cause. While the engine runs, this part controls voltage from the alternator so the battery receives the correct charge. A defective voltage regulator can leave the battery undercharged, causing an engine battery draining problem or a small engine battery not charging. If the regulator checks out, test the alternator output with a multimeter. A weak or failed alternator can cause the engine not to charge the battery, create alternator problems, and leave the battery dead after repeated use. Also inspect the battery, wiring, and electrical connections for damage or corrosion, since a battery that will not hold a charge may need replacement even when the charging system works properly. Disconnect the battery before servicing electrical components, and follow the testing specifications for your Husqvarna model. Enter your model number to find the exact replacement voltage regulator, alternator, battery, or other part made for your specific engine. Repair Clinic can help you identify the correct Husqvarna small engine part and get your charging system working properly again.
