The season of mowing is up and the grass grows so you climb on the lawn you trust --Cut the grass and turn the button.Silence.You may face one or several problems on the electrical start-up system for riding a mower.Most common electrical problems can be found in improper charging or poor battery, loose or corroded wires, electrical connectors and faulty electrical components such as start-up solenoid.The main components of the motor failure of the electric starter are Springs, magnets and brushes, which are in contact with the wires and provide the magnetic force of the engine starter.When diagnosing the engine starter problem, always start with the battery because there is not enough power and the engine starter problem cannot be diagnosed.A properly charged battery is the key to the proper running mower to start, charge and electrical systems.Before performing any diagnostic tests on the engine starter motor and related components, fully charge the mower battery with a 6 amp battery charger.The lawn mower battery is 12-There should be a Volt battery with a voltmeter reading between 12.7 to 12.9 volts when full of electricity.If the voltmeter reading of the battery is less than 12.4 Volts after fully charging using the battery charger, the battery should be replaced.Electrical connections and wiring are mechanical connections involving a metal connector that is curled or welded to a wire that is bolted to a part of an electrical component such as a switch, an engine starter motor, or a starter solenoid.Electrical connectors and wires are used to transmit power through the electrical, start-up, charging, and electrical grounding system from the battery to the battery by riding Shear law.Loose, corroded and broken electrical connectors and lines interrupt the current, providing a voltage that is not or is reduced for electrical components that cause improper operation.Clean the electrical connector with a wire brush--Track wires and connectors from battery to engine starter--Replace damaged or damaged connectors with new equipment.The starting solenoid is a remote mounted switch that powers the engine starter motor.The starter solenoid has three or four threaded electrical lugs connected to the battery, the ignition switch, the engine starter and the ground line.The starting solenoid with three lugs uses the mounting ear as the ground, of which fourUse a small convex ear as the grounding of the solenoid.Test the starting solenoid by connecting the jumper from the battery cable to another large lugs connected to the engine starting cable.If the engine starts the motor to turn, the starting solenoid needs to be replaced.If once the jumper is connected to the two large lugs on the starter solenoid, the engine starter motor will not turn, please replace the engine starter motor.The engine starter is an electric motor that is bolted to the engine starter box.The starter uses the tooth on the piston of the starter motor to turn the engine flywheel tooth and start the riding mower engine.Once the battery, electrical connector, wire and starter solenoid are tested and working properly, there may be a problem with the engine starter motor.Brushes, springs and magnets in contact with the internal wire winding of the starter motor wear, dirty or burn, preventing the starter motor from operating normally.The motor can be rebuilt or the replacement unit can be purchased.The transformation of the electric starter motor should be left to professionals with rich experience in motor maintenance.
