I've got a Wheel Horse 212-6 (1988) with a 12.5 hp FB460V Kawasaki engine. It's been great until the last mowing in 2004. It appears that the battery is not charging (less than 12 volts). I'm going to be checking the diode and voltage rectifier first before getting into the charging coil, ignition coil under the flywheel. The tractor will start with jumper cables hooked to another battery. No engagement of the electric PTO for the blades while running. (hope the clutch is still good). Was wondering if anyone out there has had similar problems with this engine type and if so what were the corrections.
