![]() Jumping/ Bypassing the solenoid Is not only a method to start the lawnmower but also a diagnostic step to confirm the malfunctioning solenoid starter. The wires’ continuity can also be contained in the same manner. Check the starter fuse and wires: Using a DMM, check the continuity of the fuse.If the motor winding is intact, the motor is good to use. Check the starter motor: Look around the engine for any electric spark or blow mark.Check the continuity using DMM on the main copper posts. Check the solenoid continuity: Touch the solenoid positive and ground terminals to a battery pack.Check the battery voltage: Using the digital multimeter in the volts setting, check the voltage across the negative and positive terminals.If you want to be quick and know the reasons, you might want to skip to the step-by-step guide. To be clear whether or not to jump a solenoid, the diagnostic part is important. In short, the solenoid cannot be blamed directly. It can be observed that the lawnmower’s failure to start can be due to several reasons and some malfunctioning components. This operation is done to get the engine started by the motor, geared to the flywheel or the engine’s crankshaft. Starter motor: When we need to power a lawnmower, the motor needs an initial boost to get air and gas to get to the first spark.It creates contact between the motor and battery, and the engine becomes operative. As soon as the key’s signal is received, the magnet becomes active due to current flow. Generally speaking, a click sound is heard as the solenoid engages. Solenoid: The electromagnet present after the battery relays the current flow from the battery to the starter engine.The 12 V is stepped up to have the capacity for the production of sparks as well. It serves as the primary source of power to operate the accessories, such as a lamp, fan, etc., and cranks up the starter mechanism to start the engine. Battery: The 12 V source that is installed in the lawnmower.What components are involved, and how to test the solenoid Involved Lawnmower Components: If the mower starts when the solenoid jumps, what does it indicate? ![]() What to do if the ignition switch is also not working?
