My Kohler K321 does not charge the battery. I measured the voltage on the AC alternator leads and get about 8-9 volts AC. The rectifier is ok as I get about 8-9 volts DC on the B+ terminal. There is an additional wire coming out of the magneto area on the engine that is capped off. I measure 28-29 volts DC on this one to ground. Does anyone know what this might be for? I thought it could be an additional lighting coil on that mag, but how could it be DC. The voltage level of 28 volts should be what I get from the AC alternator. I can't find any wiring diagrams anywhere that show additional wires. The Yahoo site has helped me some with suggestions but I am now wondering if I should remove the flywheel and check for rust or crud on the stator poles and or magnets. Anyone have any thoughts or experiences with additional wires coming out of the fan shroud area.
