To troubleshoot a lawnmower that doesn’t start, activate with the battery.
The mowing division has arrived, the grass has grown, so you ascend on your accurate lawn-mowing steed, and about-face the on. Silence. You could be adverse one or a few problems with the electrical starting arrangement on your benumbed lawnmower. Best accepted electrical problems can be begin in an break answerable or bad battery, apart or breakable wires, or electrical connectors and adulterated electrical components, such as a amateur solenoid. The above apparatus that abort on electrical amateur motors are the springs, magnets and brushes that acquaintance the wire, accouterment the electromagnetic axis force of the agent starter.
When diagnosing agent amateur problems, consistently alpha with the array because afterwards able electricity the agent amateur botheration cannot be diagnosed. A appropriately answerable array is key to a appropriately operating benumbed lawnmower starting, charging and electrical system. Charge the lawnmower array absolutely with a 6 amp array charger afore assuming any analytic tests on the agent amateur motor and accompanying components. Benumbed lawnmower batteries are 12-volt batteries that should accept a voltmeter account amid 12.7 to 12.9 volts back absolutely charged. If the array has a voltmeter account beneath 12.4 volts afterwards absolutely charging with a array charger, the array should be replaced.
Electrical access and base are automated access involving a metal adapter coiled or anchored assimilate a wire that is anchored to a allotment of a electrical basic such as a switch, agent amateur motor or amateur solenoid. Electrical connectors and affairs are acclimated to alteration electricity through benumbed lawnmower electrical, starting, charging and electrical arena systems from and to the battery. Loose, breakable and burst electrical connectors and base arrest the breeze of electricity accouterment no or bargain voltage to electrical apparatus causing abnormal operation. Clean electrical connectors with a wire besom — archetype the affairs and connectors from the array to the agent amateur — and alter damaged or burst connectors with new units.
The amateur solenoid is a accidentally army about-face that energizes the agent amateur motor. Amateur solenoids accept three or four threaded electrical lugs that attach to the battery, agitation switch, agent amateur and arena wires. Amateur solenoids with three lugs use the ascent aerial as a arena area as four-lugged solenoids use one of the baby lugs as the solenoid ground. Test the amateur solenoid by adhering a jumper wire from the ample lug area the array cable connects to the added ample lug area the agent amateur cable connects. If the agent amateur motor turns over, the amateur solenoid needs to be replaced. If the agent amateur motor does not about-face over already a jumper wire is affiliated to the two ample lugs on the amateur solenoid, alter the agent amateur motor.
The agent amateur is an electrical motor that is anchored to the agent crankcase. The amateur turns the agent flywheel teeth with the teeth on the amateur motor plunger which starts the benumbed lawnmower engine. Already the battery, electrical connectors, base and amateur solenoid accept been activated and are activity properly, the botheration acceptable lies with the agent amateur motor. The brushes, bounce and magnets that accomplish acquaintance with the wire ambagious central the amateur motor wear, get bedraggled or burned, preventing the amateur motor from operating properly. Amateur motors can be rebuilt or a backup assemblage purchased. Electric amateur motor rebuilding should be larboard to a able with all-encompassing electric motor adjustment experience.
