I have a BX23S. About 30 hrs on it. I noticed today when mowing that the preheat light on the dash was on. I went and parked it and turned off the engine. After the engine stopped the light went off about 5 seconds later. I decided to start the engine again and again the light stayed on. This time when I turned off the engine the light remained on for at least 5 minutes. I disconnected the battery cable to turn off the light. Anyone have any insight or thoughts on this? Thank you.
