    I have a 28 hp Kohler EFI and it keeps draining the battery. I'll run the mower for a while and it won't keep the battery charged. It will eventually die and when I go to start it, it just clicks. I've pulled the fuse and replaced fuse. And then it will run for a little while (after charging the battery) and then the same thing again. I've tried cleaning the connections on the three wire plug. New rectifier. Still doesn't want to stay charged. Anyone know how to fix this problem? Thanks!

    Usually when your losing battery juice that means either your fuse to your starter is bad or your starter is on its way out. I would bring it to your dealer and see what they think. Thats what was going on with my Walker.

    Why did you replace the stator and regulator? What problems were you having? Thanks!

    Everybody should have this, even if you don't own anything but a vehicle.
