Still would like to know what mower you have .
I am here to learn just as much as any one else and knowing the exception to the general rule would be very helpful as my regular diagnosing technique may need to be changed .
OK, it's an Ariens model 936042, 20hp v-twin B&S Intek, 42" deck.
I've tried turning on the headlights (it has a dedicated switch above the ignition switch) with the ignition off, and on the run position. The headlights will only turn on with the engine running.
