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.

If your machine is still under warranty, don't mess with it.

You can download a very good Workshop manual from
http://kubotabooks.com/AutoIndex/in...s/&AutoIndex=3ea0ee6e2358d18f5703663d76d826e5

To do any sort of electrical troubleshooting you need two basic tools costing about $30 total.

There are two components that would be suspect. A glow plug relay and a glow plug controller.
