FAQ

This solenoid is compatible with a wide range of lawn mowers and tractors from Craftsman, Poulan, Husqvarna, and MTD, including the popular Craftsman LT1000 series.
This part replaces OEM numbers 146154, 145673, 532146154, 178861, 168327, 1685290, 1686981, 73233, 109081X, and 2654. It also cross-references with 532192507, 192507, 110167, 28-4210, and 47-1910.
If you turn the key and hear a single 'click' sound but the engine does not crank, or if you hear nothing at all despite having a fully charged battery, the solenoid is often the culprit. Other signs include the starter motor continuing to run after the engine has started or the engine cranking intermittently.
Replacing the solenoid is a straightforward task that typically takes 15 to 30 minutes. You will generally need a basic socket set or a wrench to disconnect the battery cables and the mounting bolts. Always disconnect the negative battery terminal first before beginning the installation to prevent accidental shorting.
If the mower still fails to start, check your battery connections for corrosion, ensure the safety interlock switches (such as the seat or blade engagement switches) are functioning, and verify that the starter motor itself is not seized. It is also good practice to inspect the ground wire for any signs of damage or loose contact.
