Check the relay and/or the startex or starter motor solenoid.

Check your connections at the battery. May have a bad ground or bad battery connection. Also check to make sure new battery is good by supplementing with a jump start. If new battery is good and connections are solid, you most likely have a broken wire somewhere. The lights may only work with the mower running though. I believe on my LA105 the lights only come on with the engine running and dim/brighten with the RPM of the engine.

If your unit has OHV engine you need to check the intake and exhaust valve gap. Call your local repair shop to get numbers and check this website out. Go to smalleng.com they have a video for just what you are looking for. Good Luck...

You don't mention if they are on and are bright or are week. Do they dim when trying to cranks the motor? I would start with checking the ground wire at the battery and where it connects to the frame. Make sure both are clean. From there, have the battery tested and then the starter.

motor problem. solenoid main function to start only.
