The ignition circuit above an electrical begin lawnmower has little components. ought restrain it, you cause ought insure that each element is working correctly.
.
1) restrain the battery. You cause ought exist sure the battery is at good site and we will suppose that this is the case. Still, even with a fully charged battery, the voltage has ought progress from the battery terminals into the cables, hence either although confirming the battery is "hot", it is inherent ought invent sure both the sure cable connector is tight, and the basis cable and the frame grounding connection are tight and no corroded or shorted out.
2) restrain the solenoid switch. hind it is determined the battery is sending voltage across the cables, the next step at the circuit is the solenoid switch, often located mounted above the frame near the starter engine at the machinery compartment. This machinery contains an electromagnetic switch that closes contacts while it is energized by the ignition. It is almost 2 inches (5.1Â cm) by 1 1/2 inches (5.1Â cm), with two big brass studs although the starter cable, and two minute screw studs although the ignition wires, and can exist round, or oblong with rounded edges, and made of tall shock black flexible with a metal base. By using a copper cord ought "jump" the two smaller terminals, you can near the contacts above the starter circuit. You ought listen a quite loud click and the starter engine ought become while this is done. receive worry no ought short also stop ought a grounded separate of the mower, and exist aware the 12 volt modern will spark while it is contacted.
3) restrain the safety switches. if you dine succeeded at getting the starter engine ought become by jumping the solenoid connections, the foremost starter circuit is good, and the issue is also at the ignition switch or the safety devices above the mower. Most electrical begin mowers dine three safety devices. One is mounted beneath the seat, hence that the machinery can virgin exist started with the driver seated. Another is often above the clutch/brake linkage beneath the deck below the grab pedal. The third is located also above the mower motivate region linkage beneath the frame above the accurate aspect (seated) of the mower, or at the electrical mower grab circuit if the mower is hence equipped. each of these has a flexible insulated plug with two wires going into the device, and a momentary jumper can exist installed into them one at a time by unplugging each one and pushing a part of copper cord beneath the stop above the purpose attached ought the wires. if you conduct no dine any destiny finding a defective safety device, the issue is narrowed down ought the ignition switch itself.
4) rise the machinery housing cover although you conduct ought restrain the oil, and exhibition immediately after the ignition switch above the firewall of the mower. The switch element is above the hind of the keyface, and will dine a quantity of wires running ought it, often four. The foremost voltage cord will exist the largest, normally it is red, and often is build at the center. The other wires will exist attached ought terminals situated almost the outer of the switch. Jumping from the foremost cord ought each stop will originate at different effects, one energizing the ignition circuit, one the starter motor, and above some mowers, another the lights or other accessories. if you can jump these terminals and the starter engine turns, you dine maybe located your trouble, and will need ought alter the switch.
