Troy Bilt Bronco riding mower 18 hp Koehler - electrical issue - mower will start and run
Mower will start and run for 20 seconds.
When the engine cuts out, the headlights are out w/ the key in the middle position (lights/run)
Mower will not start when no headlights; replaced ignition switch - same result
If headlights are on, the mower will start and run for 20 seconds. Any thoughts?
